PRISM: Prioritized Channel Importance with Semi-supervised Domain Adaptation for Cross-Subject EEG Emotion Recognition
arXiv:2607.00358v1 Announce Type: new Abstract: Electroencephalogram (EEG) captures endogenous brain activity with high temporal fidelity and holds substantial promise for precise emotion decoding. However, channel redundancy and pronounced inter-subject variability remain key obstacles to scalable generalization. To address these limitations, we propose a novel framework termed PRioritized channel Importance with Semi-supervised doMain adaptation (PRISM), enabling label-efficient cross-subject emotion decoding. On the channel side, PRISM assigns differentiable, data-dependent channel weights
The continuous advancements in AI and neuroscience, coupled with increasing computational power, are enabling more sophisticated approaches to decoding complex biological signals like EEG for practical applications.
Precise emotion decoding from EEG, especially across different individuals, has profound implications for human-computer interaction, mental health monitoring, and advanced AI applications that require understanding human emotional states.
This framework offers a significant step towards more robust and generalizable EEG-based emotion recognition, moving past current limitations of channel redundancy and inter-subject variability that have hindered wider adoption.
