EPECT: An Eigenvalue-Guided Positional Encoding Classification Transformer for Cross-Subject EEG-fNIRS Decoding
Decoding mental states from non invasive neural recordings is central to brain computer interface research. Multimodal acquisition that combines electroencephalography (EEG) and functional near infrared spectroscopy (fNIRS) couples the high temporal resolution of EEG with the spatial specificity of fNIRS, compensating for the individual limitations of each modality. While such hybrid systems achieve strong intra s...
