Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Summary

DisCo-MLP, a simpler model, matches Transformer performance for electroencephalography (EEG) brain-computer interfaces. Effective RSVP-EEG decoding relies on signal structure, not just complex models.

Neuroscience

Biomedical Engineering

Background:

Rapid serial visual presentation (RSVP) is key for electroencephalography (EEG)-based brain-computer interfaces (BCIs).
Single-trial decoding in RSVP-EEG is challenging due to signal overlap and entanglement.
Existing Transformer-based models like DisCo-Former show promise but suffer from attention collapse.

Purpose of the Study:

To develop and evaluate DisCo-Former, a Transformer-based framework for RSVP-EEG decoding.
To investigate the impact of architectural complexity versus signal structure modeling on BCI performance.
To introduce DisCo-MLP, a simpler MLP-based variant, and compare its efficacy to DisCo-Former.

Main Methods:

Developed DisCo-Former, integrating trend-periodicity disentanglement, channel-level embeddings, and contrastive learning.
Introduced DisCo-MLP by removing the Transformer encoder from DisCo-Former.
Evaluated both models on two datasets using three regimes, including within-subject decoding.

Main Results:

DisCo-Former surpassed existing approaches but exhibited attention collapse.
DisCo-MLP matched or outperformed DisCo-Former across datasets and evaluation regimes.
Within-subject decoding achieved mean AUCs of 0.94-0.98, exceeding baselines.

Conclusions:

Model effectiveness in RSVP-EEG decoding is driven by modeling signal structure rather than architectural complexity.
Simpler models, guided by neurophysiological priors, offer a practical route to state-of-the-art EEG-based interfaces.
DisCo-MLP demonstrates that complex architectures are not always necessary for high performance in RSVP-EEG decoding.
