Foundation Time-Series Model Research Agenda
Visual Map


Collaboration
If this direction resonates with you, I would be happy to talk with like-minded people, collaborate on research, and work on use-cases together.
Ideas are not the bottleneck. Hands are. Time-series modeling should be moving at least as fast as vision, audio, and robotics.

Summary
A real foundation time-series model is not just a larger forecaster. It should operate on always-on streams, maintain latent state under continuous updates, use context, handle multivariate and irregular data, preserve enough dense numeric detail for generation and editing, represent multiple plausible futures, and eventually support actions, control inputs, interventions, and counterfactual prediction.
The working test for every source in this area is simple:
Does this source close one of the bottlenecks that blocks
a general latent-state time-series model, or is it only a local
forecasting/classification/generation improvement?This page is the central organizing frame for the wiki’s time-series foundation-model work. It defines the slots into which source pages, topic pages, entities, and durable ideas should be mapped.
What’s Wrong With The Current Time-Series Deep Learning? remains the landmark position source for why observation forecasting is too narrow and why latent-state modeling matters. It answers a narrower recurring question inside this broader agenda.
Aionoscope and LeNEPA now provide the local MILETS 2026 instrumentation/method pair for the representation-learning part of this agenda. Aionoscope tests whether latent process state is accessible under controlled synthetic probes; LeNEPA tests whether a no-augmentation next-latent SSL recipe with temporal SIGReg can transfer across a real ECG signal family and Aionoscope Diag without retuning its method-specific recipe. SensorFM adds the large closed-corpus wearable-sensor scale case: missingness-aware masked reconstruction over 5M participants transfers across 35 health tasks, while still lacking a public benchmark or action-conditioned interface.
Practical North Star: Digital-World Robots
The practical target is to build digital-world robots: agents for digital, organizational, and cyber-physical systems that can observe, remember, simulate, and act. A foundation time-series model is not the whole robot. It is the state and dynamics layer underneath the agent.
The robotics analogy is intentional but bounded. A physical robot has sensors, embodiment, control inputs, and a world model. A digital-world robot has telemetry, logs, traces, business events, topology, calendars, customer or user context, configuration, deployment machinery, safety constraints, and typed intervention capabilities. Its “body” is the system it can observe and affect.
This is not limited to SRE or telecom. Those are the current focus because they provide dense time-series streams, explicit system structure, and relatively clear intervention surfaces. The same frame should eventually cover digital marketing, sales operations, supply chains, finance, industrial systems, and safety-critical infrastructure such as nuclear power plants. The common requirement is a model that can represent system state, evaluate plausible futures, and reason about action consequences.
The digital-world frame is broader than observability alone. CWM is the current code-domain precedent: it treats Python execution and agentic repository work as action-observation trajectories. That is useful evidence for the data contract, but it remains outside numeric time-series modeling because its observations are program states, files, command output, and tests rather than telemetry streams.
MiniMax Sparse Attention adds a different long-context scaling lesson from the agentic-model side: if digital-world robots need million-token histories, the bottleneck is not only model state but also the attention and serving kernels that read that history. For this agenda it is a serving/architecture analogy, not evidence that sparse block selection preserves telemetry state.
Gated DeltaNet supplies the scalar-gated recurrent-memory baseline for this long-context branch, while Gated DeltaNet-2 separates erase and write in the fixed-size state. Oryx, Hybrid Associative Memories, and HOLA add a complementary long-context lesson: exact attention or explicit KV memory can be routed, thresholded, or kept under a fixed top- budget rather than uniformly applied. For this agenda, that is a plausible mechanism for protecting rare events, exogenous context, topology changes, and action windows, but only after benchmark probes show that the selector does not erase predictable but decision-critical state. HOLA’s rule is a useful low-cost signal, but it measures recurrent-state update magnitude rather than downstream control value.
Agentic World Modeling makes the broader taxonomy explicit: digital world models operate under software laws such as API contracts, UI state machines, file-system logic, permissions, and error branches. That is directly relevant to digital-world robots, but it also sharpens the missing piece for this agenda: SRE and operations need the same action-conditioned simulator contract over numeric telemetry, graph time series, event streams, and typed interventions.
Agentic Automata Learning adds a controlled negative test for the LLM-agent side of this picture. Even when the hidden environment is an exact DFA and the agent receives crisp membership/equivalence-query feedback, LLM agents still struggle to plan informative queries, reuse accumulated evidence, and infer a stable hidden model as state complexity grows. For digital-world robots, this is a warning: a tool-calling LLM with long context is not automatically the latent-state or dynamics layer.
Awesome Agentic Time Series is the time-series-specific survey/list counterpart. It frames agentic time-series systems as closed-loop temporal decision systems with perception, reasoning, planning/action, memory/knowledge, temporal world models, and reliability constraints. For this agenda, it is a current field map and candidate-ingest queue, not primary evidence that any listed system already solves action-conditioned TSFM modeling.
World Model for Robot Learning Survey adds the robotics-specific boundary: for embodied agents, visual future prediction is not enough unless the predicted futures remain action-sensitive, physically executable, and useful for policy evaluation or planning. The TSFM translation is that intervention-conditioned rollouts should be judged by downstream decision utility, not only by passive forecast error.
On Training in Imagination adds a data-economics boundary for that same interface: the transition model and the reward or outcome model can have different sample costs, scaling exponents, and noise/bias profiles. For digital-world robots, the analogous split is telemetry/action-transition data versus human, SLO, or expert reward labels.
In agenda terms, the foundation time-series model supports this interface:
observations + context + action history
-> latent state
-> plausible futures under candidate interventions
-> selected action or control inputThat is why this agenda tracks streaming state, context, multi-modal future distributions, native multivariate encoding, event streams, causality, counterfactuals, dynamic compute, and benchmarks. Each slot is a missing capability on the path from passive time-series modeling to action-conditioned digital-world agents.
Existing local anchors:
- AI North-Star Terminology maps broad goal terms such as AGI and SAI back to measurable time-series and world-model interfaces.
- Observability Time Series covers the closest SRE/telemetry testbed.
- World Models provides the general state, future, and action-consequence frame.
- Digital World Models covers the software-defined branch of action-conditioned simulators.
- Slow Thinking For Robotics And Time Series connects physical robotics, telecom, and operational time-series systems through layered state/action interfaces.
Capability Target
The target model should expose at least these capability surfaces:
| Capability | Required Interface | Why It Matters |
|---|---|---|
| Forecasting and imputation | history, context -> future observation distribution | Basic utility, but not enough for system understanding. |
| Classification and anomaly detection | history, context -> labels, regimes, events | Tests whether representations preserve discriminative state. |
| Reasoning and question answering | history, context, query -> answer or explanation | Needed for human-facing analysis and incident understanding. |
| Generation | conditions -> plausible time-series samples | Requires calibrated distribution modeling, not only point forecasts. |
| Modification and editing | history, edit instruction -> modified series | Requires preserving original dense detail while changing selected factors. |
| Control | latent state, context, candidate actions -> future trajectory distribution | The central world-model target: choose actions by evaluating consequences. |
The capability target immediately creates a representation tension. A purely semantic embedding may be excellent for labels or decisions, but too lossy for generation and editing. A purely dense reconstruction embedding may preserve values while failing to capture regimes, causal variables, or action-relevant state. The research agenda is to make that tradeoff controllable rather than accidental.
Learning is Forgetting gives a useful adjacent language-model frame: better representations can be understood as lossy compression of objective-relevant information. For this agenda, the open question is which objective makes a time-series model compress toward action-relevant latent state rather than only average next-observation prediction.
TimeCraft and its referenced Microsoft Research papers sharpen the generation part of the interface. TimeDP conditions on target-domain prototypes, BRIDGE conditions on text and prototypes, TarDiff and OATS optimize synthetic samples for downstream utility, CaTSG separates observational, interventional, and counterfactual generation, Diff-MN targets continuous generation from irregular observations, and DiGA plus MarS move into financial-market simulation. The key lesson is that generation should be classified by its conditioning contract, not only by sample realism.
Problem Map
1. Streaming State, Long Context, And Constant Updates
Real systems produce data continuously. The context is not just long; operationally it is unbounded, with a finite retained window and new observations arriving all the time. A useful model must update state at least as fast as real time, avoid recomputing the full history after every sample, and preserve the information needed for future decisions.
Relevant existing pages:
- Latent-State Time-Series Modeling
- Streaming Latent-State Updates
- Extra-Long Context For Time Series
- Time-Series Scaling And Efficiency
- Efficient Recurrent Sequence Models
- Observability Time Series
Useful evidence so far: recurrent or compact-state backbones, contiguous patch masking, efficient decoding, state-space models, rank compression, selective recurrent memory editing, and sleep-time consolidation all help with parts of the problem. They do not by themselves prove always-on latent-state maintenance.
Audio Interaction Model is demoted to a context-level real-time interaction warning. Its explicit serving loop, silence/response decision, FIFO asynchronous inference, first-chunk latency, stall-rate reporting, and proactive trigger evaluation are useful benchmark prompts, but the paper relies on heavy audio preprocessing, synthetic stream composition, history-review probes, and scheduling rather than solving retained-state growth. The TSFM version should keep the serving-contract questions while rejecting the curated-data workaround as a core solution.
Awesome Agentic Time Series reinforces the evaluation boundary for this slot: memory is a capability layer only when it changes future temporal behavior in an auditable way. Context-window summaries, retrieved cases, and procedural traces should therefore be tested for stale-memory failures, regime retention, action relevance, and state-update cost rather than counted as solved memory by design.
Language Models Need Sleep is the clearest current analogy for infinite-context streaming: an SSM-attention hybrid spends extra compute before a finite attention window is evicted, writes a better fast-weight state, then continues with cheap wake-time prediction. The TSFM version would be a learned state-refresh step over recent numeric observations, events, context, and action history before raw samples leave the retained window.
FADE adds a parameter-level continual-learning analogy: memory horizons can be adapted rather than fixed globally. That is not yet TSFM evidence, but it sharpens the requirement that online systems need selective forgetting of stale mappings while retaining stable dynamics and rare safety-relevant state.
TurboQuant adds a serving-memory warning for this slot: retained-state compression must beat hardware-native baselines after dequantization, latency, throughput, and memory-pressure regimes are counted, not only reduce bytes.
Latent Context Language Models and Compress & Attend Transformers add upstream language evidence for learned context compression before or during decoding. The TSFM analogue is a retained-history interface where raw recent observations stay high resolution while older history becomes compressed latent state. This remains adjacent until tested on multivariate numeric streams, event streams, exogenous variables, control inputs, and interventions.
Gated DeltaNet-2 adds an adjacent memory-editing hypothesis for this slot. It shows that, in language-model recurrent state, separating key-side erase from value-side write can reduce interference under fixed state size. The TSFM translation is not “use this architecture as-is,” but “test whether stale-association erasure and new-observation commitment need separate controls when state must preserve rare regimes, channel relationships, events, and action history.”
Streaming Latent-State Updates now owns the dedicated page for online inference cost, retained memory, state refresh, abstain/trigger behavior, and real-time serving contracts.
2. Multi-Modal Future Distributions
This agenda uses multi-modal here in the probability-distribution sense, not the data-modality sense. Many real systems have several plausible futures. A model that averages incompatible futures can be numerically smooth and operationally wrong.
This matters for forecasting, generation, modification, and control. A control system needs to know not only the expected future, but also which future regimes are plausible under uncertainty and which actions change the probability mass.
Relevant existing pages:
- Probabilistic JEPA Predictor Using Flow Matching
- Latent-State Time-Series Modeling
- World Models
- Energy-Based Models
Useful evidence so far: probabilistic forecast heads, flow matching, diffusion-style generation, energy-based framing, and latent-variable world models are all partial routes. World Models is the historical action-conditioned example: an MDN-RNN models a distribution over the next latent state, and temperature exposes the tradeoff between exploitable deterministic dreams and overly noisy imagined environments. The missing test is whether the model preserves multiple decision-relevant future states rather than only calibrated marginal forecasts.
VJEPA is the clearest current JEPA-side bridge for this slot. It turns a deterministic latent point prediction into an explicit conditional distribution over future latent states, connects time-indexed latent prediction to Bayesian filtering, and supports sampled belief rollouts for stochastic model-predictive control. BJEPA adds a modular Product-of-Experts prior that can represent goals, physics, feasibility, or safety constraints separately from reusable learned dynamics.
The crucial limitation is also exactly aligned with this agenda. VJEPA’s evaluated head is an independent diagonal Gaussian: it is unimodal and mainly represents latent predictive or aleatoric uncertainty. The architecture can host mixtures, flows, or other expressive families, but the current results do not show distinct future modes. The later ICML poster also shows that probabilistic JEPA is not uniformly better than deterministic JEPA: VJEPA leads the five-environment linear Noisy-TV study at moderate nuisance scale, while deterministic JEPA is strongest and most stable at the hardest scale. This source therefore strengthens the research requirement without closing it.
Probabilistic JEPA Predictor Using Flow Matching turns that requirement into a properties-first experiment. It treats conditional flow matching over future JEPA latent trajectories as the primary architecture candidate, compares it against direct raw-trajectory flow, and requires oracle-decoder ceilings, separated-mode calibration, tail-risk probes, decoder-use ablations, action ranking, and quality/latency frontiers before the JEPA latent route receives credit.
For this agenda, a credible multi-modal-future result MUST report more than CRPS, quantiles, or sample diversity. It SHOULD test separated regime coverage, probability calibration, invalid between-mode trajectories, tail-risk recall, multivariate constraint preservation, and whether candidate actions or interventions move mass among future regimes correctly.
ELF adds a cross-modality substrate analogy rather than direct evidence for this slot: text generation can stay in a continuous embedding-space flow and decode to tokens only at the final step. It remains adjacent until a TSFM demonstrates multiple calibrated numeric future modes under text/context conditioning and downstream utility.
Latent Thought Flow adds an adjacent latent-trajectory analogy for this slot: a reward-proportional posterior over hidden reasoning paths is conceptually close to preserving multiple candidate futures, but the paper tests answer reasoning rather than calibrated numeric trajectories or action-sensitive futures.
The Flexibility Trap adds proposal-coverage evidence from diffusion language models: a flexible confidence-driven reveal order can look competitive at Pass@ while flattening as the sampling budget grows. For this slot, one-sample forecast quality is therefore insufficient; a time-series generator should report whether distinct valid regimes, rare trajectories, and action-dependent futures remain reachable under its commitment schedule.
Why Diffusion Models Don’t Memorize is warning evidence for this slot: diffusion/flow generators may show useful sample quality before later memorization, so future-distribution evidence should include checkpoint age and copying/leakage probes, not only quality or calibration metrics.
3. Data Diversity, Curriculum, And Long Tail
Real time-series corpora are useful-signal-poor. Normal operation dominates, while failures, regime changes, interventions, tail users, rare devices, unusual weather, unusual demand, and edge-case patient states are sparse.
Dynamic Curriculum Learning For JEPA frames the local idea: use model surprise to spend training compute on windows that still carry learning signal. Distribution Priors In Self-Supervised Learning adds the caution: anti-collapse losses and batch construction can impose hidden distribution priors that are harmful under long-tailed data.
Research should be scored by whether it improves rare-state preservation, not just average loss. A method that accelerates training on common patterns but erases rare regimes moves away from the foundation-model target. LLMs as Noisy Channels adds the parallel scaling caveat: average-loss scaling can be monotonic only while the useful signal stays ahead of accumulated noise.
The internal discussion behind the dynamic-curriculum idea sharpens this slot. The problem is not only that real corpora are noisy; it is that normal operation can dominate so heavily that the model learns to treat failures, regime shifts, and corner cases as ignorable noise. The research agenda should therefore split the work into two questions: dataset-level curriculum over unlabeled useful-signal-poor corpora, and model-level robustness so the encoder does not discard rare correlated events when the data distribution is unknown.
Implicit Curriculum Hypothesis adds a checkpoint-monitoring version of this slot. It is LLM-only evidence, but it suggests that a useful TSFM curriculum should not only improve average loss; it should make latent-state capabilities emerge in a measurable order, with absolute thresholds for rare regimes, channel coupling, context use, and intervention-sensitive state.
Adjacent evidence from Synthetic Data for any Differentiable Target suggests a stronger but expensive version of curriculum scoring: estimate an example or window by its downstream training effect through a differentiable probe. For TSFMs this is only a hypothesis, because DPG is text/SFT evidence, but it sharpens the requirement that rare-state curricula report metric-target overfitting and hidden representation drift alongside matched-compute gains.
Conditional Autoencoders for Electrical Consumption is a narrow energy-domain example: expert-conditioned residual latent spaces made sparse holidays, bridge days, snow or cold snaps, and vacation effects visible, but the evidence is a single passive national-load dataset rather than a scalable curriculum method.
Bitter Lesson for Data Filtering adds the compute-scale caution: in LLM pretraining, ordinary quality filters can help at small compute, but larger models trained longer may extract more value from the raw data pool. The TSFM translation is that filtering should be compared against no-filter or loose-filter baselines at matched FLOPs, and the winning policy may change with model size and training duration.
LLMs as Noisy Channels adds an upstream scaling-law warning: more tokens can eventually add more noise than signal when the data-noise exponent dominates the signal exponent. The TSFM version should not assume that adding more normal-operation windows always helps; scaling studies should track useful-signal density, corrupt observations, repeated steady state, missingness, and rare-regime retention.
Scaling Laws, Carefully adds the compute-allocation version of the same warning. In data-limited scaling, repeated tokens are not equivalent to unique tokens, and larger models can be more sensitive to repetition. The TSFM analogue is repeated normal-state telemetry: a training run can be FLOPs-matched while still optimizing around the wrong effective-data count if rare structured windows and intervention windows are not tracked separately from redundant normal windows.
No Filter adds the benchmark-mismatch caution: an English-only VLM data filter can improve ImageNet/COCO while degrading cultural and socioeconomic coverage. The TSFM analogue is a sampler that improves average forecast error while erasing tail devices, tenants, regions, regimes, interventions, or pre-failure states.
SensorFM is useful positive evidence for scale and diversity in this slot because it trains on >1T minutes from >100 countries and >20 devices. It is also a caution: a private wearable-user corpus can still be long-tailed, missingness-heavy, and biased by who owns and wears the devices, so data volume is not a substitute for subgroup and rare-state reporting.
The publishable test is matched-compute, not just “more filtering.” A useful result should report rare-event or rare-state metrics, normal-behavior retention, corrupt-window robustness, no-filter and dedup-only baselines, and whether the same surprise policy transfers between multivariate time series and image/video trajectories.
4. Augmentation-Free Or Dataset-Aware Self-Supervision
Time-series augmentations are not universal. Jitter, cropping, scaling, warping, masking, permutation, and frequency transforms can be valid for one domain and destructive for another. A foundation model trained across many datasets cannot assume one augmentation family is always label-preserving or state-preserving.
This creates two routes:
- build a large library of dataset-aware augmentations and metadata rules;
- prefer objectives that need fewer handcrafted augmentations, such as latent prediction, masked modeling with careful grounding, next-state prediction, or world-model objectives.
Self-Supervised Representation Learning, JEPA, and Latent-Space Predictive Learning are the current anchors. A source helps this problem when it reduces dependence on brittle augmentation assumptions while preserving state variables and dense numeric detail.
Learn From Your Own Latents And Not From Tokens is useful here as adjacent theory: it shows a synthetic hidden hierarchy where own-latent targets avoid an exponential surface-token sample-complexity cost. The agenda should not treat that as time-series evidence until the mechanism survives irregular sampling, long-tailed regimes, exogenous variables, and dense numeric-value preservation.
NextLat moves that own-latent intuition into a practical autoregressive Transformer objective: predict the model’s own next hidden state while retaining next-token supervision. The TSFM transfer is to test next-state or next-hidden objectives that require fewer handcrafted augmentations, but only if they preserve rare regimes, dense numeric detail, exogenous context, and action history.
LeNEPA partially closes the augmentation-free branch in a narrow time-series SSL setting: the tested recipe removes handcrafted augmentations and stop-gradient/EMA targets while keeping useful frozen-probe gains under a fixed-recipe PTB-XL/Diag stress test. It does not close the broader slot until the same recipe is tested on multivariate, irregular, event-stream, long-tailed, and action-conditioned data.
SensorFM is not augmentation-free in the same sense, but its LSM-2/AIM lineage treats natural missingness and artificial masking as a unified reconstruction interface. That partially closes the missingness-aware SSL branch for regular minute-level wearable streams, while leaving event streams, irregular timestamps, and action-conditioned settings open.
5. Context Interface: Channel Context And General Context
Context has two separate roles.
Channel context describes what each channel means: metric name, unit, sensor type, topology node, service, region, product, physiological variable, protocol layer, or actuator. Without it, a multivariate model can see numbers but not know what the numbers are.
General context describes the system and situation: season, holiday, maintenance window, deployment, weather, user segment, market condition, topology, known incident, experiment setting, or operating mode.
Context is Key is the clean benchmark anchor for text-conditioned forecasting, while CHARM is the local source for channel-description-conditioned multivariate representations. These are partial answers: they show that context can matter, but they do not yet provide a full context interface for high-dimensional streaming systems with actions and event streams.
Research should be scored by which context type it handles and whether context is actually necessary for the target, not merely decorative metadata.
6. Representation Quality: Semantic State Vs Dense Numeric Detail
The model needs semantic state for regimes, events, causal variables, and decisions. It also needs dense numeric detail for high-fidelity forecasting, generation, imputation, and modification.
EIDOS is the local time-series anchor because it predicts latent representations while grounding them back to observations through a reconstruction head. LeNEPA adds the no-augmentation next-latent SSL variant and exposes intermediate-layer frozen probes. Aionoscope adds the diagnostic benchmark: component identity can be easier to recover than dense timing, phase, amplitude, frequency, and regime parameters. NextLat adds a complementary hidden-state supervision lesson from language models: ordinary output accuracy can hide poor internal map quality, so representation probes and latent rollout diagnostics should accompany forecast/generation scores. Reconstruction Or Semantics? shows the robotics version of the same conflict: semantic latents can be more policy-relevant than reconstruction latents, but dense fidelity still matters for geometry and contact. Implicit Curriculum Hypothesis adds an upstream diagnostic: internal representations can predict later capability trajectories, so TSFM layer/probe APIs should be evaluated not only for final transfer but for whether they forecast future state-skill emergence.
Aristotelian Representation Hypothesis adds the measurement hygiene for this slot: representation-similarity probes should report calibrated nulls and distinguish global geometry, local neighborhood structure, and downstream dense-state utility. For temporal data, those nulls must preserve dependence structure rather than arbitrarily shuffling timestamps.
The unresolved target is inference-time control over what information is preserved. A model should not use one fixed representation policy for every query. Forecasting a smooth seasonal signal, editing a spike, detecting an incident, and choosing an intervention may require different layers, heads, or latent subspaces.
Research directions to track:
- auxiliary losses that keep dense numeric information available in deeper layers;
- intermediate-layer access rather than only final-layer representations;
- depth-wise attention or attention-residual mechanisms that let later layers retrieve earlier representations;
- task-conditioned readout from semantic and dense states;
- probes that test reconstruction, generation, modification, decision relevance, and capability-emergence timing separately.
The local JEPA-curriculum notes add a concrete NEPA-style warning for this slot: in a next-embedding-prediction time-series setup, moving the target from patch-independent embeddings to contextual or internal-layer representations made latent prediction worse when those targets appeared to mix away local differences.
7. Anti-Collapse Regularization
Avoiding constant collapse is necessary but not sufficient. A representation can be non-collapsed and still learn the wrong factors, such as slow distractors, common regimes, or nuisance variables.
Representation Collapse tracks this cluster. JEPA Slow Features is the warning source, while LeJEPA, When Does LeJEPA Learn a World Model?, LeWorldModel, and LeNEPA anchor Gaussian or distribution-regularized JEPA/NEPA-style approaches. Sensorimotor World Models adds the action-grounded alternative: inverse dynamics can prevent full collapse by requiring latent transitions to recover the logged action, but it can also intentionally collapse variables outside the action repertoire. The identifiability result is especially useful because it distinguishes a non-collapsed embedding from a linearly usable latent state under stated Gaussian/OU assumptions. The Hidden Uniform Cluster Prior adds the long-tail warning: the anti-collapse prior itself can bias what the model preserves.
For foundation time-series models, the key question is whether regularization preserves rare regimes, cross-channel deviations, intervention effects, and multiple plausible futures. SMWM makes this sharper: an action-recovery objective may preserve controllable state better than an arbitrary distribution prior, but only if the logged actions are rich enough and the evaluation still checks action-irrelevant safety or diagnostic variables.
8. Patch Size, Dynamic Tokenization, And Point-Wise Numeric Embeddings
Fixed patch size is a hidden modeling assumption. The right temporal resolution varies across datasets, across channels, and even inside one signal. A quiet hour of server metrics and a bursty incident window should not be encoded at the same density.
The agenda needs both extremes:
- adaptive patching for redundant or low-information spans;
- point-wise numeric embeddings for cases where every sample may matter.
ReinPatch and Kairos are current adaptive-tokenization anchors. EIDOS is the point-wise numeric-token anchor. Number Tokenization tracks related scalar encodings such as Fourier, bit-level, and typed numeric embeddings.
Compute Optimal Tokenization adds an upstream scaling-law constraint: if granularity changes, the unit used to state scaling laws must change too. For text, the paper argues for bytes per parameter rather than tokens per parameter. A time-series foundation model needs the analogous unit before claiming compute-optimal patching or compression, and that unit may differ for dense samples, sparse event streams, high-channel telemetry, and action logs.
Scaling Laws, Carefully adds the fitting caveat for that unit choice. A patching or tokenization result should not infer a compute-optimal granularity from one run; it should expose the compression or active-token target as a scaling variable and test whether the fitted optimum is stable across model size, effective data, and fit region.
A source helps this problem when it makes token granularity data-dependent without erasing change points, spikes, missingness, local causal events, or channel-specific deviations.
9. Native Multivariate Encoding And High-Channel Scaling
Multivariate time series cannot be reduced to a slogan like “embed separately” or “embed together.” Channel-independent models improve transfer and serving simplicity, but can miss cross-channel dynamics. Naive channel-dependent attention can become too expensive and noisy.
High-Dimensional Time Series Forecasting is the current topic page. U-Cast and Time-HD anchor thousand-channel passive forecasting. Toto, Toto 2.0, and BOOM anchor the observability version at grouped-query scale.
Graph Structure As Transformer Context tracks the topology-conditioned branch: when channels are nodes and edges in a known graph time series, the model should compare graph-context interfaces instead of flattening topology into anonymous channel order.
Topological Neural Operators adds a scientific-ML boundary case: when quantities naturally live on different supports, such as nodes, edges, faces, or volumes, native structured encoding should preserve that support instead of flattening it into anonymous channels. This is adjacent to graph time series, not proof of action-conditioned TSFM control.
SensorFM adds a smaller but concrete native multivariate case: 34 wearable numeric features from five sensor families are encoded jointly over 24-hour windows. It partially closes the wearable-sensing version of multivariate representation learning, but not high-channel telemetry, graph time series, or arbitrary channel schemas.
Research should be scored by:
- whether it is channel-independent, channel-dependent, factorized, hierarchical, graph-conditioned, or retrieval-based;
- whether it preserves cross-channel interactions;
- whether it scales to hundreds, thousands, or tens of thousands of channels;
- whether it handles channel metadata and topology;
- whether it stays passive or introduces actions/control inputs.
10. Time Representation And Irregular Event Streams
Regular time series can often use sample index as a proxy for time. Irregular time series and event streams cannot. The model may need elapsed time, calendar time, sampling rate, event order, duration, missingness, seasonality, and asynchronous channel updates.
T-Rep is the current source for learned time embeddings. FlowState is relevant because it uses coefficient-space and continuous basis decoding for flexible sampling rates. The broader wiki still needs a dedicated topic page for time representation across regular samples, irregular time series, event streams, continuous time, and calendar time.
Research helps this problem when it makes time a first-class input rather than an accidental positional index.
MIRA is now the strongest local medical example for this slot: Continuous-Time RoPE handles real-valued timestamps, a Neural ODE extrapolation block evolves latent state to arbitrary target times, and frequency-specific MoE layers specialize over temporal regimes. Diff-MN complements it from the generation side by using irregular observations to condition continuous trajectories through diffusion-generated MoE-NCDE dynamics. Both partially close irregular-time modeling, but neither yet demonstrates always-on streaming state with explicit action, control-input, intervention, or treatment channels.
11. Dynamic Compute Allocation
Easy windows and hard windows should not receive identical computation. Dynamic compute can happen through sparse experts, recursive or looped depth, pause or thinking tokens, adaptive inner steps, hierarchical compression, or energy-based search.
Current local anchors:
- Mixture Of Experts
- Time-Series Scaling And Efficiency
- Hierarchical Modeling with a Fixed FLOPs Budget
- Energy-Based Models
- EBT
- Looped Transformers And Test-Time Memory
- MoDA
- mHC
- Hyperloop Transformers
- ELT
- Language Models Need Sleep
- LT2
- DMax
- iLLaDA
- The Flexibility Trap
- The Thinking Pixel
- The Illusion of Superposition
- Latent Thought Flow
- Looped World Models
- NextLat
- Variable-Width Transformers
- Scaling Laws, Carefully
H-Net, ConceptMoE, Compute Optimal Tokenization, and Scaling Laws, Carefully are useful architecture and scaling analogs for learned hierarchy and implicit compute allocation. Scaling Laws, Carefully is especially a methodology source: a dynamic-compute claim should compare allocation frontiers across budgets and effective-data regimes, not only one matched-FLOPs point. EBT adds an explicit search path: score candidate predictions with an energy function, then spend more optimization steps or more candidate samples when the prediction is hard. The time-series-specific target is stronger: allocate compute to spans, channels, regimes, and candidate futures that matter for latent-state maintenance and control.
Scaling Test-Time Compute for Agentic Coding is an adjacent runtime-compression example: long action-observation traces become more useful after structured summarization, selection, and refinement. The transfer target is not raw prompt summarization of telemetry, but learned state compression that preserves action-relevant facts under a compute budget.
Latent Context Language Models adds the compressed-global-view plus exact-local-expansion pattern through its EXPAND(i) agent harness. Compress & Attend Transformers adds a test-time chunk-size knob. Both are useful dynamic-compute analogies, but the TSFM version needs learned budget allocation based on event density, state uncertainty, anomaly risk, or action relevance rather than a manually chosen text chunk size.
DiffusionBlocks adds an adjacent training-memory route: local denoising objectives can reduce full-depth backprop memory and recurrent-depth BPTT cost, but pretrained conversion, privacy, and numeric time-series state preservation remain untested.
DMax adds the decoding-side counterpart to the training-memory and looped-depth branches: aggressive parallel diffusion decoding can reduce serial generation steps only when intermediate predictions remain self-correctable. For TSFMs, treat OPUT/SPD as adjacent evidence until numeric horizon, event-stream, and action-conditioned rollout benchmarks show that soft intermediate states preserve rare regimes, dense values, exogenous variables, and interventions under matched latency.
iLLaDA adds the from-scratch scale signal for that diffusion-language branch: an 8B masked diffusion LM can be trained on 12T tokens with variable-length generation and strong base-model benchmark results. For this agenda it stays adjacent because the evidence is text-only, the scoring protocol includes a confidence-based multiple-choice surrogate, and the instruct model still trails Qwen2.5 Instruct; it does, however, make diffusion sequence models worth tracking for future horizon-generation and revisable-rollout experiments.
The Flexibility Trap separates the dynamic-compute budget across phases: sequential left-to-right rollouts during RL can improve exploration and exact credit assignment, while parallel decoding remains available at inference. The TSFM test is whether decision-critical timestamps or action consequences should be exposed sequentially during training while low-entropy future regions are generated in parallel, with forward passes, wall-clock cost, memory, coverage, and leakage all matched.
The Thinking Pixel adds a continuous-latent dynamic-compute analogue: sparse recursive adapter experts refine visual diffusion tokens inside joint attention. For TSFMs, the useful transfer is not text-to-image quality; it is the question of whether spans, channels, regimes, or candidate futures should receive extra routed latent updates before output. The missing test is matched-latency numeric and action-conditioned evidence plus adaptive halting.
The Illusion of Superposition is the caution attached to that whole branch. Soft latent thoughts and fine-tuned latent reasoning can collapse or shortcut even when the interface is continuous. TSFM dynamic-compute claims should therefore include no-latent/no-loop ablations and probes for whether hidden state preserves uncertainty over regimes, events, channels, and candidate futures.
Latent Thought Flow is the positive counterpart to the Illusion warning. It explicitly trains a reward-proportional sampler over variable-length hidden trajectories, so the TSFM analogue would be to allocate hidden compute to candidate latent-state updates or candidate futures under a quality/cost reward. The agenda should still treat this as adjacent until matched wall-clock, no-latent/no-loop, reward-noise, and state-probe tests exist for numeric time-series or action-conditioned rollouts.
Looped World Models is the first source in this looped-depth cluster that directly targets a world-model transition interface: observations and actions update latent state, the recurrent block can spend variable compute per transition, and deferred decoding rolls candidate action sequences in latent space. For TSFMs this partially closes the dynamic-compute and action-conditioned rollout shape outside numeric time series, while leaving public artifacts, matched latency, dense numeric preservation, and operational telemetry benchmarks open.
Variable-Width Transformers adds a static hidden-width allocation baseline for this slot. It partially closes the narrow architecture question of whether nonuniform depth-wise capacity can beat a uniform Transformer under matched parameters, but it is still language-model evidence: no learned per-input router, numeric time-series benchmark, action-conditioned rollout, or realized heterogeneous-kernel latency result is shown.
Recurrent Transformer depth, depth-state retrieval, residual-stream capacity, loop-boundary supervision, and energy-based optimization loops belong here as adjacent dynamic-compute mechanisms, not as automatic progress on the curriculum slot. Universal Transformers, Huginn, Latent Thoughts, The Illusion of Superposition, Latent Thought Flow, LT2, MoDA, mHC, Hyperloop Transformers, ELT, LoopFormer, Parcae, and Sparse Looped LMs are promising for real-time deployment, early exit, uncertainty signals, linear/sparse looped serving, depth-memory retrieval, residual-state capacity, and bounded-memory inference, but they need matched comparisons against wider or deeper unique-weight models and direct evidence that extra depth compute, cheaper mixers, depth communication, loop-boundary supervision, or residual-stream width preserves decision-relevant temporal state. LT2, Parallel Samplers, and The Recurrent Transformer sharpen the serving contract: dynamic compute must be evaluated against realized throughput, key-value cache traffic, recurrent-state memory, OOM frontiers, and exact decoding schedules, not only nominal FLOPs. MoDA and mHC add the same warning for inter-layer communication and residual-stream capacity: depth retrieval or matrix residual state may help only if the cache, memory bandwidth, and kernel budgets are explicit. ELT adds a useful visual-generation example where intermediate loop exits are trained directly, but TSFMs still need calibrated stopping rules and numeric-state preservation probes. Extra recurrence inside an Energy-Based Transformer is especially a design risk: the EBT inference procedure already has an iterative energy-gradient loop, so the first question is whether the energy landscape or candidate search is the bottleneck.
Language Models Need Sleep adds a consolidation-time version of this question for SSM-attention hybrids. Extra compute is spent before context eviction to write a better fast-weight state, not during every later prediction. For TSFMs, the analogous design would be an online state refresh step at window boundaries in an infinite stream, but the evidence remains language/synthetic until it is tested on numeric streams, event streams, and action histories.
Dragon Hatchling adds a stronger fast-state architecture hypothesis: make the mutable recurrent state a central part of the model, keep sparse positive activations, and probe individual state/synapse behavior. For this agenda it is important but adjacent evidence. It sharpens the streaming-state and dynamic-compute slots, while still missing numeric time-series, event-stream, and action-conditioned tests.
Titans and ATLAS add a complementary memory-at-test-time route. For this agenda, the interesting question is whether memory updates preserve rare regimes, cross-variate relationships, exogenous context, and intervention history, not only whether they improve recall-style long-context tasks.
HRM, TRM, GRAM, URM, and Universal Transformers Need Memory are adjacent recursive-reasoning evidence. They are useful for latent-state refinement, supervision, memory-slot, halting-budget design, and GRAM-style width-based latent-trajectory sampling, but still puzzle evidence until tested on numeric time series, event streams, or action-conditioned trajectories.
Loop convergence itself may be useful as a diagnostic. If a recurrent block needs unusually many iterations before representations stabilize, that can act as an uncertainty or failure signal; if additional loops saturate after a small number of iterations, test-time compute has diminishing returns and should be capped.
Candidate sources to ingest later:
Think before you speak: Training Language Models With Pause Tokensfor delayed next-token prediction.Attention Residualsfor learned access over previous layer outputs.Inner Thinking Transformerfor adaptive internal depth.
These candidates should not be treated as wiki evidence until they have source pages.
12. Benchmarks: What Level Of Modeling Is Tested?
The benchmark question is not “which model has the best score?” It is “what level of modeling did the score test?”
The agenda should separate at least these levels:
| Level | Question | Failure If Missing |
|---|---|---|
| Shape forecasting | Can the model extrapolate visible morphology? | Repeats curves without understanding process state. |
| Latent-state prediction | Does it track regime, constraints, and hidden state? | Good forecast error but weak rare-event and decision behavior. |
| Context use | Does context change the predicted distribution correctly? | Numeric history is treated as complete when it is not. |
| Multi-modal futures | Does it preserve multiple plausible futures? | Averages incompatible outcomes. |
| Causal/counterfactual reasoning | Does it represent intervention consequences? | Confuses passive events with actions. |
| Control utility | Does it choose or rank better actions? | Forecasts well but cannot act. |
Time-Series Benchmark Hygiene is the current page. Future benchmarks should report whether they test observation forecasting, state prediction, context sensitivity, rare-regime preservation, high-dimensional channel interaction, irregular/event-stream handling, generation fidelity, modification fidelity, or action-conditioned rollout.
Aionoscope partially fills the latent-state diagnostic level: it supplies exact categorical and dense latent labels from a controlled generator and shows that dense state can remain weakly accessible even when coarse component presence is easy. LeNEPA is the matching method-side protocol reminder: fixed-recipe reuse is different from fully tuned leaderboard performance.
Agentic Automata Learning is not a time-series benchmark, but it is a useful evaluation-design warning: final success should be decomposed into information gathering, evidence integration, hypothesis construction, query efficiency, and non-informative action rate. A TSFM control benchmark should make the analogous decomposition for telemetry observations, event streams, and typed interventions instead of only reporting closed-loop reward.
13. Causal Structure, Counterfactuals, And Control
A foundation time-series model should eventually support counterfactual prediction: what would happen under a different action, control input, or intervention? This is distinct from conditioning on exogenous future events.
Causal Time Series is currently small. CauKer uses causal structure for synthetic time-series generation, while TimeOmni-1 includes causal discovery as a reasoning target. Action-Conditioned Time-Series Datasets tracks the dataset side.
The world-model test is whether the model can evaluate future trajectories under candidate actions. Passive forecasting, even when probabilistic and high-dimensional, does not close this problem.
Awesome Agentic Time Series is useful here because it names planning/action and temporal world models as separate layers. The wiki should keep that separation: workflow planning, tool routing, or model orchestration can be agentic without proving that the system has a transition model capable of counterfactual action-conditioned rollout.
CaTSG is the TimeCraft branch that most directly touches this slot because it explicitly generates observational, interventional, and counterfactual time series. TarDiff is adjacent because it optimizes synthetic samples for downstream prediction targets rather than causal validity. DiGA and MarS are useful financial-market precedents because their generated order-flow or market trajectories support scenario and what-if analysis, but the action/control semantics are still domain-specific and not a general TSFM transition interface.
Source Assessment Rubric
Every new paper, dataset, model, or benchmark in this agenda should be evaluated with the same rubric.
| Field | Question |
|---|---|
| Problem block | Which bottleneck above does it address? |
| Interface | What are the inputs and outputs? History only, context, channel metadata, event stream, action, control input, intervention, query, edit instruction? |
| Data regime | Regular or irregular, univariate or multivariate, low-channel or high-dimensional, single-domain or diverse, balanced or long-tailed? |
| Evidence type | Model result, benchmark, dataset, theory, position paper, ablation, or architecture analogy? |
| Capability surface | Forecasting, imputation, classification, reasoning, generation, modification, control, or evaluation hygiene? |
| Slot-level verdict | For each agenda slot: closes, partially closes, adjacent, warning, or insufficient evidence. |
| Missing pieces | What must be added before it supports a foundation time-series model? |
Use this verdict vocabulary consistently:
- Closes: directly solves a required interface or evaluation gap with convincing evidence.
- Partially closes: solves a narrow version, usually passive, low-dimensional, single-task, or missing actions/context.
- Adjacent: useful mechanism or analogy from another domain.
- Warning: exposes a failure mode, bias, or benchmark caveat.
- Insufficient evidence: uses nearby language or improves a local score without enough evidence to count as progress on the agenda slot.
Verdicts are per slot, not per source. If one paper helps context conditioning
but says nothing about control, the context row can be partially closes while
the control row is insufficient evidence. If another paper is mainly valuable
because it shows a benchmark or representation failure, the affected slot should
be marked warning rather than merged into a generic source-level verdict.
Current Research Coverage Matrix
This matrix is intentionally selective. It lists only landmark or important
source pages, or tight source clusters, that have at least one closes or
partially closes slot-level verdict. Pure warnings, adjacent analogies,
diagnostics, normal-priority sources, and insufficient-evidence entries belong
on the relevant source and topic pages, not in this central agenda table.

Open Questions
- What is the minimal benchmark that tests always-on streaming state updates instead of static windows?
- How should a model expose multiple plausible futures in a way that is useful for action selection?
- Can one representation preserve semantic state and dense numeric detail, or do we need task-conditioned access to multiple layers or latent streams?
- What is the right context schema for channel identity, global context, topology, event streams, and actions?
- Can dynamic patching and point-wise numeric embeddings coexist in one model without brittle routing?
- When should a streaming TSFM spend compute on state consolidation before window eviction rather than on larger memory, retrieval, prediction-time loops, or wider recurrent state?
