Violin plots showing zero-shot identification accuracy for visual stimulus decoding in ECoG data using brain-aligned semantic vectors derived from the fMRI V4 region. a CLIP-based and b GloVe-based semantic vectors with optimal α parameters determined from the fMRI results. The individual data points from 4 subjects (E1–E4) are overlaid on violin plots. The white circles indicate shuffled control data, demonstrating chance-level performance.
