摘要

•Two two-stage algorithms are developed to detect spikes in epileptic scalp EEG.•A convolutional neural network (CNN) is used to extract node embeddings.•Graph neural networks (GNNs) are applied on functional connectivity (FC) maps.•Attention mechanism is used to bypass the feature engineering step in the last point.•Higher average precision (AP) is achieved compared to standard architectures.
