ST-BiT: Spatio-Temporal Bipartite Transformer Network for Interaction-Preserving EEG-Based Dementia Subtyping

EEG-based dementia classification often degrades under clinically realistic subject-wise evaluation due to non-stationarity and large inter-subject variability. A key modeling limitation is relation compression: many EEG-GNN pipelines encode functional connectivity as scalar edge weights and blur in
