Dive into Waves: Morlet Spectral Transformer for Cross-Subject Emotion Decoding from EEG
Researchers have developed a new model called the Morlet Spectral Transformer (MST) for decoding emotions from EEG data across different subjects. The MST utilizes Morlet wavelet tokenization to better represent time-frequency structures in brain rhythms and incorporates frequency-specific spatial projection to capture band-specific patterns. This approach aims to overcome limitations of existing methods, such as large pretrained models that require extensive data and frequency-domain encoders that struggle with representation mismatches.
