Argus: A CNN-LSTM Architecture for Real-Time Seizure Detection in Long-Term EEG Monitoring
Steven E. Haworth1, Santiago Philibert2, Cameron Brace3
Presents Argus, a multi-scale convolutional and bidirectional LSTM network with an attention mechanism for automated seizure detection. Trained and evaluated on the Temple University Seizure Corpus (TUSZ v1.5.2) using a 22-channel TCP bipolar montage at 200 Hz, achieving 98.06% ROC-AUC. The architecture is designed with clinical deployment in mind, prioritizing low false positive rates in continuous long-term monitoring settings. No manuscript in preparation at this stage.

Classifying Conscious Experience Using Topological EEG Features in Healthy Populations
Steven Haworth, collaborators at Harvard and Beth Israel Medical Center
Investigates the electrophysiologic and network-level features distinguishing conscious experience (CE) from no conscious experience (NCE) during NREM stage 2 and 3 sleep using HD-EEG combined with machine learning classification. In a serial-awakening paradigm across 140 participants and 699 awakenings, spectral power, functional connectivity via lagged coherence, and graph-theoretic metrics including modularity, global efficiency, and rich-club coefficient were extracted and screened using false discovery rate correction. A probabilistic ensemble classifier achieves ROC-AUC 0.80 and average precision 0.80 with stable 5-fold participant-level cross-validation, with the largest discriminating effects observed in posterior alpha, delta, and gamma-to-alpha power ratios.
