Fig. 8: Brain alignment progressively enhances feature unit category discriminability.
From: Brain-aligning of semantic vectors improves neural decoding of visual stimuli
Kernel density distributions of the F statistics measuring category discriminability across feature units for the original CLIP features and brain-aligned variants. Stronger brain alignment (smaller α) systematically shifts the distributions rightward, indicating improved discriminability. The dashed vertical lines indicate the mean F statistic for each condition.
