Abstract

Recent claims about the superiority of deep-nets to model human vision are based on the reproduction of either (a) neural recordings from different brain layers or (b) high-level behaviors included in Brain-Score. However, high correlations in such tasks do not guarantee the functional similarity of the underlying mechanisms in models and humans. In particular, appart from exceptions (like your work ;-), not many people is looking at the bottleneck of artificial systems as characterized by low-level visual psychophysics. In this talk we present stimuli for 20 different experiments that highlight basic color/texture/motion perception facts, and how the trends of the artificial responses can be used to assess the similarities with human vision.
