EEG-Titans: Long-Horizon Seizure Forecasting via Dual-Branch Attention and Neural Memory
Abstract: Accurate epileptic seizure prediction from electroencephalography (EEG) remains challenging because pre-ictal dynamics may span long time horizons while clinically relevant signatures can be subtle and transient. Many deep learning models face a persistent trade-off between capturing local spatiotemporal patterns and maintaining informative long-range context when operating on ultralong sequences. We propose EEG-Titans, a dualbranch architecture that incorporates a modern neural memory mechanism for long-context modeling. The model combines sliding-window attention to capture short-term anomalies with a recurrent memory pathway that summarizes slower, progressive trends over time. On the CHB-MIT scalp EEG dataset, evaluated under a chronological holdout protocol, EEG-Titans achieves 99.46% average segment-level sensitivity across 18 subjects. We further analyze safety-first operating points on artifact-prone recordings and show that a hierarchical context strategy extending the receptive field for high-noise subjects can markedly reduce false alarms (down to 0.00 FPR/h in an extreme outlier) without sacrificing sensitivity. These results indicate that memory-augmented long-context modeling can provide robust seizure forecasting under clinically constrained evaluation

EEG-Titans: Long-Horizon Seizure Forecasting via Dual-Branch Attention and Neural Memory
Introduction and Background
The problem of epileptic seizure prediction from long-term multichannel EEG remains challenging due to the subtle, extended, and non-stationary nature of pre-ictal biomarkers. Most existing deep learning methods have struggled to capture both local spatiotemporal patterns and long-range temporal dependencies, especially under realistic deployment constraints such as causality preservation and low false alarm rates in noisy conditions. EEG-Titans addresses this gap with a dual-branch neural architecture that integrates a ShallowConvNet-based spatial tokenizer with the Titans Memory-as-a-Gate (MAG) temporal backbone, optimizing for both efficient long-term modeling and sensitivity-first operation.
Seizure Prediction Protocol and Data Preparation
Seizure, pre-ictal, and safety intervals are defined with rigorous respect to temporal causality and noise control. The pre-ictal interval comprises a 30-minute window ending 5 minutes prior to seizure onset (the seizure prediction horizon, SPH). To prevent label leakage, a 1.5-hour safety margin is excluded around each cluster of seizures, and inter-ictal periods are conservatively selected from clean segments far from any seizure activity.
Figure 1: Schematic of the seizure prediction protocol. Pre-ictal and inter-ictal periods are separated with a 1.5-hour safety margin, with a 5-minute SPH prior to seizure onset.
This protocol ensures that the chronological order is preserved in training and evaluation, with only subjects and intervals meeting strict artifact and metadata criteria included in analysis.
EEG-Titans Architecture
EEG-Titans processes raw EEG in three stages:
- Spatial Tokenization: The ShallowConvNet extracts frequency- and topology-aware tokens from 5-second EEG segments. It applies wide temporal convolutions, spatial mixing, and log-variance pooling, yielding compressed yet discriminative representations.
- Temporal Backbone (MAG): The token stream is processed by the Titans MAG block, which fuses a local attention branch (causal sliding-window attention) with a global, adaptive neural memory. The local branch captures short-term anomalies, while the memory branch maintains slowly evolving state summaries over arbitrarily long contexts. A learnable gating mechanism dynamically fuses the two branches.
- Classification Head: The fused output is transformed into a probability estimate for imminent seizure within the pre-ictal window.
Figure 2: Overall EEG-Titans architecture. ShallowConvNet serves as a spatial tokenizer; memory-augmented Titans backbone models long-range dynamics and produces seizure probability estimates.
Figure 3: Titans MAG block combines local causal attention for short-range dependencies and a recurrent neural memory for capturing global trends, fused through a learnable context gate.
The MAG's memory state is updated by an element-wise gated combination of prior memory and current input; the gate is learned and can adapt across features. This flexible dual-branch design permits both sensitive detection of abrupt pre-ictal changes and robustness against spurious noise, which is directly evaluated in difficult artifact-rich and pediatric environments.
Evaluation and Results
Performance is measured on the CHB-MIT scalp EEG dataset using segment-level sensitivity and false positive rate per hour (FPR/h). The chronological hold-out protocol maintains temporal order and challenges the system to generalize to unseen seizure clusters, emulating real deployment.
Key results include:
- Average segment-level sensitivity: 99.46% across 18 subjects.
- Stable operation (100% sensitivity, <0.2 FPR/h) in 16/18 subjects.
- For challenging artifact-heavy (CHB15) and pediatric (CHB06) cases, the system initially produced elevated false alarm rates. Extension of the input context (from 60s to 300s) for CHB15 reduced FPR/h from 3.87 to 0.00 and increased sensitivity from 90.34% to 99.86%, demonstrating robust false alarm rejection through adaptive temporal integration.
- Benchmark comparisons indicate competitive or superior performance to recent Transformer and CNN-LSTM pipelines, with EEG-Titans performing on par with methods requiring heavier explicit time-frequency preprocessing.
Architectural Insights and Ablation Analysis
Ablation experiments clarify the contributions of the temporal backbone and spatial tokenizer:
- With the ShallowConvNet tokenizer fixed, replacing Titans with a standard LSTM or attention-only backbone reduces FPR/h but not segment-level sensitivity. The MAG memory consistently suppresses false positives relative to other architectures, especially in the presence of nonstationary noise.
- The tokenizer supplies EEG-domain inductive bias, allowing the temporal processor to focus on enforcing consistency rather than basic feature extraction.
- The gating mechanism in MAG provides selective, data-driven weighting of short- vs. long-term evidence, supporting both rapid detection and resistance to artifacts, rather than merely smoothing the signal.
Implications and Future Directions
Integration of Long-Horizon Temporal Modeling
By decoupling local and global processing and leveraging adaptive memory, EEG-Titans achieves scalable, causal modeling of long-range EEG trends with resource efficiency unattainable by vanilla Transformer attention. This dual-branch strategy aligns with the requirements of anticipation tasks where early detection under weak, slowly evolving signals is critical, and suggests applicability to other EEG domains such as motor intention or cognitive event probability estimation.
Patient-Specific Adaptation and Generalization
The direct impact of temporal context adaptation on false alarm rates demonstrates that context length is a key clinical hyperparameter. Future research should explore automated, uncertainty-aware online policies for selecting temporal integration scales, integrating artifact detection and demographic inference for optimal patient-level operation.
Toward Trustworthy Clinical Deployment
EEG-Titans's performance heterogeneity in various subject groups underscores the importance of individualized calibration and the need for interpretability and fairness analyses at the subgroup level. Further work is required to ensure transparency (e.g., through attention or memory attribution) and rigorous external validation, particularly in ambulatory or cross-population scenarios.
Relation to Broader Long-Sequence Modeling Trends
The memory-augmented architecture provides an alternative to state space models and efficient attention approximations for long-sequence processing. Combining differentiable memory with structured latent dynamics—a direction shared with emerging Mamba- and SSM-class models—may yield further gains in robustness and computational tractability for continuous biosignal forecasting.
Conclusion
EEG-Titans demonstrates that dual-branch, memory-augmented modeling provides a practical solution for long-horizon seizure prediction from EEG, balancing ultra-high sensitivity and flexible false alarm control under realistic, causality-preserving protocols. The evidence supports the broader utility of hybrid memory/attention architectures for medical time series and anticipatory neural decoding, with future directions pointing toward adaptive, interpretable, and individually calibrated systems for trustworthy real-world deployment.

Overview
This paper is about predicting epileptic seizures before they happen by reading brain signals recorded with EEG (electroencephalography). The authors built a new AI model, called EEG-Titans, that tries to catch tiny warning signs that can appear many minutes before a seizure, even when the signals are noisy and the important patterns are spread out over long periods of time.
Key Objectives
The researchers set out to answer simple but tough questions:
- Can we predict seizures early (5–30 minutes before they start) using scalp EEG?
- Can a model watch both short, quick changes and slow, long-term trends at the same time?
- Can we do this in a way that works realistically over time, without “cheating” by peeking at future data during training?
- Can we keep sensitivity (catching true seizure warnings) very high while keeping false alarms low, especially for patients with noisy recordings?
How They Did It
The team combined smart data preparation with a dual-branch AI model that looks at brain signals in two different ways—like using both a magnifying glass and a long-term diary.
Data and Labeling
- They used a well-known dataset called CHB-MIT, which contains many hours of EEG from children with epilepsy.
- From 24 original subjects, they selected 18 who had consistent recordings and enough seizure events to evaluate properly over time.
- They focused on the “pre-ictal” period, which is the 30 minutes before a seizure. To be realistic and give time for action, they ignored the last 5 minutes just before the seizure (this is called the Seizure Prediction Horizon, SPH).
- To avoid mixing normal brain activity with seizure-related changes, they removed 1.5 hours of EEG around each seizure cluster, so the “inter-ictal” (normal) data is clean.
The Model: Two Branches Working Together
Think of EEG-Titans like a two-tool system:
- A “spatial tokenizer” first listens to the EEG from multiple channels, a bit like tuning a radio to different frequencies and directions across the head. It turns raw signals into compact “tokens” that capture useful patterns.
- A “temporal backbone” then reads those tokens over time using two branches:
- Short-term attention: like a spotlight scanning the last few seconds to catch quick spikes or odd shapes.
- Neural memory: like a diary that keeps track of slower changes building up over minutes. It updates gently, remembering important trends while ignoring random noise.
- A smart gate blends the two: if quick changes look meaningful and match the longer build-up, the model raises the seizure probability. If quick changes look like random noise, the memory branch can tone them down.
Turning Predictions into Practical Alarms
To avoid triggering alarms from one noisy moment:
- The model looks at a short window of recent predictions and averages the top few scores, making alarms more stable.
- Each patient gets their own alarm threshold (because EEGs vary a lot from person to person).
- There’s a 30-minute “cooldown” after any alarm, so you don’t get spammed by repeated alerts from the same episode.
Evaluation That Respects Time
- They trained the model on earlier recordings and tested it on later ones, keeping the time order. This prevents accidental “future knowledge.”
- They focused on segment-level sensitivity, meaning: does the model consistently spot most of the pre-ictal segments, not just trigger one alarm?
- They measured false positives per hour (FPR/h), which tells you how many wrong alarms you’d get in an hour of normal EEG.
Main Findings
Across 18 patients:
- The model reached an average segment-level sensitivity of 99.46%. For 16 out of 18 patients, it was 100%.
- The average false alarm rate was 0.371 per hour. Most patients had low false alarms (often below 0.2 per hour), but two patients were outliers.
Two key lessons stood out:
- For a very noisy patient (CHB15), increasing the short-term context from 1 minute to 5 minutes made a huge difference: false alarms dropped from 3.87 per hour to 0.00, while sensitivity jumped to 99.86%. Longer context helped the model see that brief bursts of noise didn’t match a steadily growing pre-seizure pattern.
- For a very young patient (CHB06), the model kept perfect sensitivity but had higher false alarms (0.90 per hour), likely because pediatric EEG can be highly variable and seizures were very short. This suggests some patients may need special tuning.
An additional “ablation” test compared versions of the model:
- The neural memory branch helped reduce false alarms compared to using only attention or only an LSTM (a common type of recurrent neural network), while keeping sensitivity high. This supports the idea that memory-augmented long-range modeling stabilizes predictions.
Why It Matters
This research shows a practical way to predict seizures early, with high coverage and careful respect for time. The dual-branch design—fast attention plus slow memory—seems especially good at telling the difference between true warning signs and random noise. It can:
- Improve safety by catching most pre-seizure periods.
- Reduce alarm fatigue by lowering false positives, especially if we adjust the context length for noisy patients.
- Fit real-life use by avoiding methods that are too slow or require looking far into the future.
Implications and Potential Impact
- For patients and caregivers: More reliable early warnings could help people get to a safe place or prepare medication before a seizure happens.
- For clinicians: A “sensitivity-first” setup reflects real-world priorities—missing a seizure is worse than a few false alarms. Still, the model shows concrete ways to cut false alarms with patient-specific adjustments.
- For AI in healthcare: Memory-augmented models that handle long-range context efficiently can be useful beyond seizures, like in other brain or heart monitoring tasks where important changes build up slowly.
- For future work: Automating the choice of context length and adding pediatric-specific calibration could make the system even more robust and fair across different patients.
In short, EEG-Titans is a promising step toward trustworthy, long-horizon seizure forecasting: it listens closely, remembers wisely, and balances quick signals with slow trends to keep people safer.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a concise list of concrete gaps and open questions that remain unresolved and can guide future research:
- External validity beyond CHB-MIT: No evaluation on independent datasets (e.g., TUH, EPILEPSIAE, Melbourne) or adult/intracranial EEG, leaving cross-site and cross-population generalization unknown.
- Patient-level generalization: The chronological hold-out is within-subject; it remains unclear whether a single global model generalizes across unseen patients without subject-specific calibration.
- Selection bias from subject exclusions: Six subjects were excluded (montage heterogeneity, insufficient clusters, missing metadata); the impact of these exclusions on representativeness and performance estimates is not quantified.
- Montage constraints: Restricting to 18 common bipolar channels improves consistency but limits applicability to centers with different montages; robustness to alternative/variable montages is untested.
- Real-time feasibility and resource costs: No measurements of latency, memory footprint, energy use, or throughput for streaming inference on edge/wearable hardware despite long-context claims.
- Event-level performance: Results emphasize segment-level sensitivity; event-based metrics (per-seizure sensitivity, time-in-warning, time-to-alarm distribution) are not reported.
- Alarm timing and anticipation: Early warning horizons and alarm lead-time variability relative to onset are not analyzed, impeding assessment of practical intervention windows.
- Operating characteristic curves: Lack of ROC/PR curves or operating-point sweeps under the same protocol limits interpretability of sensitivity–specificity trade-offs and comparison with prior work.
- Comparability to prior SOTA: Reported FPR/h differs markedly from some literature; absence of re-evaluation of baselines under the same chronological protocol hinders apples-to-apples comparisons.
- Confidence intervals and statistical testing: No per-subject or cohort-level CIs, variance across runs, or statistical tests, limiting conclusions about robustness and significance.
- Threshold calibration: Patient-specific thresholding via coarse grid search (0.05 steps) may be suboptimal; calibration reliability and overfitting risks to validation splits are not examined.
- Distribution shift and drift: Model robustness under day-to-day non-stationarity, medication changes, sleep–wake cycles, and longer-term drift is not evaluated; no continual/adaptive learning strategy is proposed.
- Memory behavior characterization: The effective time horizon, retention/forgetting dynamics, and susceptibility to memory contamination by artifacts are not analyzed; no reset policy for memory across seizure/post-ictal transitions in continuous monitoring is specified.
- Parameter-matched ablation: Ablations do not control for model capacity; it is unclear how much of the gain stems from the memory mechanism versus parameter count or architecture depth.
- Hyperparameter sensitivity: Key design choices (local attention window, token length, memory size, soft-fusion window W and top-K) lack sensitivity analyses or principled selection guidance.
- Labeling assumptions: Performance sensitivity to pre-ictal window (35–5 min), SPH=5, SOP=30, and the 30-min seizure clustering rule is not tested; clinical variability in pre-ictal duration remains unaddressed.
- Safety margins and real-world transfer: A 1.5-hour safety margin around seizures is enforced for training/evaluation; performance without such margins (as in real deployments) is unknown.
- Artifact handling: Apart from basic filtering, no explicit artifact detection/suppression (e.g., EMG/eye/motion) is integrated; robustness to artifact bursts and different noise sources is only qualitatively discussed.
- Pediatric heterogeneity: Elevated FPR in very young subjects (e.g., CHB06) suggests age-dependent non-stationarity; no dedicated pediatric calibration protocol or age-stratified analysis is provided.
- Context-length adaptation: Extending context from 60 s to 300 s reduces FPR in CHB15, but there is no automatic, causal policy to adapt context online or analysis of the trade-off with warning latency.
- Interpretability: No channel-, frequency-, or time-level attribution for predictions or memory states; clinical validation of learned biomarkers is lacking.
- Probability calibration and uncertainty: Predicted probabilities’ calibration quality is not assessed; there is no uncertainty/OOD detection to defer decisions in artifact-heavy or ambiguous segments.
- Imbalance and augmentation: The impact of using overlapped positives only during training on generalization/calibration is unclear; alternative class-imbalance strategies (e.g., focal loss, cost-sensitive learning) are not explored.
- Sleep and behavioral covariates: No modeling or stratification by sleep stage/time-of-day, despite their known influence on seizure likelihood and EEG background.
- Refractory-period choice: The 30-minute refractory period’s effect on FPR/h and missed alarms is not ablated; optimal refractory durations may vary by patient/context.
- Preprocessing portability: Notch filtering is fixed at 60 Hz; performance in 50 Hz regions or with different hardware noise profiles is unknown.
- Seizure-type stratification: Lack of analysis by seizure morphology (focal vs generalized), duration, or localization obscures condition-specific strengths/weaknesses.
- Continuous deployment protocol: Procedures for memory resets, handling post-ictal transition, and safe re-entry to inter-ictal operation in uninterrupted monitoring are not specified.
- Reproducibility: Training details (seeds, epochs, early stopping), code/models, and exact hyperparameters are not released, limiting independent verification and extension.
- Ethical and fairness considerations: The paper flags outlier cases but does not quantify subgroup fairness (age, sex), user burden (alarms/day), or patient-reported outcomes in a deployment scenario.
- Alternative long-sequence baselines: No direct empirical comparison to modern state-space models (e.g., Mamba/SSMs) under the same protocol, despite positioning memory as a long-context solution.
- Multimodal integration: Potential gains from adding ECG/EOG/accelerometry for artifact disambiguation and context are not explored.

- Potential tools/products: Data commons; annotation tooling; cohort curation and provenance tracking.
- Assumptions/Dependencies: Funding, ethical approvals, de-identification; interoperability across devices/montages.
- Edge AI hardware/software: Low-power deployment of MAG on wearables
- Use case: Optimize Titans/MAG inference on microcontrollers or neural accelerators to extend battery life while maintaining long-context memory.
- Potential tools/products: Kernel libraries for causal attention + memory; quantization/pruning strategies; on-device schedulers.
- Assumptions/Dependencies: Hardware vendor collaboration; acceptable latency/accuracy trade-offs; robust OTA updates.
- Clinical trial platforms: Sensitivity-first studies and alarm management
- Use case: Orchestrate trials that prioritize sensitivity, track alarm fatigue, and evaluate subject-level adaptation (e.g., context length policies).
- Potential tools/products: Trial management software; standardized endpoints; remote monitoring integration.
- Assumptions/Dependencies: Regulatory design approvals; patient adherence; multi-site coordination.
Notes on overarching assumptions and dependencies
- Data realism and generalization: Results are derived from CHB-MIT (pediatric, limited to 18 subjects after channel standardization and sequence constraints). Adult and broader ambulatory generalization needs validation.
- Labeling protocol: Pre-ictal defined as 35–5 minutes before onset; 5-minute SPH, 30-minute SOP, and 1.5-hour safety margins. Clinical utility may vary with different horizons and care pathways.
- Patient heterogeneity: Elevated false positives in artifact-heavy/non-stationary cases (e.g., CHB15, CHB06) highlight the need for subject-specific adaptation.
- Resource constraints: Long-context modeling must meet edge compute and battery requirements for wearables; memory gating helps but still needs optimization.
- Regulatory and clinical adoption: Diagnostics require rigorous trials, interpretability, and trust frameworks; near-term positioning should be “adjunct decision support,” not standalone diagnostic.
