SUMMARY:Vision Seminar: Navve Wasserman - Interpreting Visual Representati
 ons in the Human Brain
LOCATION:Columbia Zuckerman Mind Brain Behavior Institute\, 3rd Floor\, L3
 -079
DESCRIPTION:Navve will present two recent projects that develop automated 
 and scalable approaches for discovering and interpreting visual representa
 tions in the human brain. BrainExplore (https://navvewas.github.io/BrainEx
 plore/) addresses the challenge of searching the vast space of possible vi
 sual representations by using data-driven decomposition of fMRI activity t
 o discover candidate neural patterns\, identifying the natural images that
  most strongly activate them\, and automatically generating and quantitati
 vely evaluating natural-language explanations of their visual meaning. Thi
 s framework enables large-scale discovery of thousands of interpretable pa
 tterns across the visual cortex. Building on the challenge of reliably ide
 ntifying what these neural patterns actually represent\, BrainCause (https
 ://yuvalgol123.github.io/BrainCause/) moves from activation-based discover
 y toward causal validation: it uses generative models to construct control
 led stimuli\, including counterfactual edits and semantic negatives\, to t
 est whether a brain region responds specifically to a target visual concep
 t rather than to correlated visual or semantic features.\n\nhttps://cail.c
