A Multimodal Sequence-to-Sequence Model for Cross-Subject Prediction of Brain Responses to Naturalistic Stimuli
This research proposes a sequence-to-sequence Transformer to predict whole-brain fMRI responses to naturalistic movies by autoregressively processing visual, auditory, and language inputs. It uses specialized models like VideoMAE and HuBERT for feature extraction and integrates narrative summaries to capture complex temporal dependencies in brain activity.
