Original description

Traditional video-induced physiological datasets predominantly rely on coarse, whole-trial labels, which introduce Temporal Label Noise. To bridge this gap, we present FIRMED (Fine-grained Immediate Recall-based Multimodal Emotion Dataset).

Figure 1: Experimental paradigm for FIRMED data collection, encompassing the multi-session design, trial timeline (baseline, stimulus, immediate recall replay, rest), multimodal signal acquisition, and the multi-dimensional annotation structure.
