# EEGSurvNet: A Deep Survival Model to Predict Time-to-Seizure After EEG

![Figure1_Discrete-time](https://cdn-uploads.huggingface.co/production/uploads/68f50e480a62655974ebb216/Nylq4cUHQzwcJb5prOD1U.png)

## Model Description

EEGSurvNet predicts the long-term risk of seizure recurrence through time after routine EEG. The input is a 60s EEG segment with 19 channels in spectrogram format (see below for specifications). The output is the logit of the seizure recurrence hazards at 6 discrete time intervals.

**Paper**: [Development and validation of a deep survival model to predict time to seizure from routine electroencephalography](https://onlinelibrary.wiley.com/doi/10.1002/epi.70101?af=R) (Epilepsia, 2026)

**Repository**: [GitLab Repository]() - See README for full documentation and preprocessing code

## Usage - WIP

**Note**: See the [GitLab repository README](https://gitlab.com/chum-epilepsy/epi_surv/README.md) for complete preprocessing pipeline, BIDS format requirements, and dataloader examples.

## Training Data

- 1,014 routine EEG recordings from 994 patients
- Tertiary care center (CHUM, Montreal)
- Temporal split: Training/validation (Jan 2018 - Sep 2019), Testing (Sep-Dec 2019)
- Median follow-up: 2.2 years (training)

## Performance

- 2-year integrated AUROC: 0.69 (95% CI: 0.64–0.73)
- C-index: 0.66 (0.60-0.73)
- Maximal AUROC at 2 months (0.80)
- Outperforms spike-based predictions
