AMultimodal BiMamba Network with Test-Time Adaptation for Emotion Recognition Based on Physiological Signals

Emotion recognition based on physiological signals plays a vital role in psychological health and human-computer interaction, particularly with the substantial advances in multimodal emotion recognition techniques. However, two key challenges remain unresolved: 1) how to effectively model the intra-modal long-range dependencies and inter-modal correlations in multimodal physiological emotion signals, and 2) how to address the performance limitations resulting from missing multimodal data. In this paper, we propose a multimodal bidirectional Mamba (BiMamba) network with test-time adaptation (TTA) for emotion recognition named BiM-TTA.
