Global Adaptive Transformer for Cross-Subject EEG Classification [Paper]

Core idea: cross attention for distribution alignment

This model is somewhat bad, trying the effect of attention on domain adaptation.

Abstract

• We propose a Global Adaptive Transformer, named GAT, for domain adaptation in EEG classification, where cross attention is used to align marginal distributions of source and target domains (subjects).
• Parallel convolution branches are used to capture temporal and spatial features from raw EEG signals.
• We design an adaptive center loss to align the conditional distribution of EEG features.

Requirements:

• Python 3.10
• Pytorch 1.12

Datasets

• BCI_competition_IV2a - acc 76.58% (hold out)
• BCI_competition_IV2b - acc 84.44% (hold out)

Hope this code can be useful. I would appreciate you citing us in your paper. 😊
