SAIN: A Hierarchical Dynamics-Aware EEG–fNIRS Framework for Continuous Affect Estimation
Continuous affect estimation from electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) aims to recover time-varying Valence and Arousal from heterogeneous physiological signals. Their differences in channel organisation, response latency, temporal statistics, and noise characteristics make hom...
