EmoMind: Decoding Affective Captions from Human Brain fMRI

In three linesEmoMind decodes affective captions directly from brain fMRI signals. The system first retrieves a neutral scene description from brain-decoded visual features, then rewrites it using a continuous 34-dimensional emotion vector extracted from the same fMRI recording. Evaluated on two independent emotion fMRI datasets, EmoMind outperforms GPT-4 with discrete emotion labels across all validation axes.
