EmoMind: Decoding Affective Captions from Human Brain fMRI

In three linesEmoMind decodes affective captions directly from fMRI signals in two stages: retrieving semantically grounded neutral descriptions, then rewriting using a continuous 34-dimensional emotion vector. Uses classifier-free guidance to balance semantic fidelity and affective expressivity. Outperforms GPT-4 on two independent fMRI emotion datasets.
