Chapter 4: Object Recognition - Play Psych Mun

Constraints: Coordinate systems cont.• Farah prefers the Multiple Viewer-Centeredrepresentation option because:– Position, size, and orientation invariance shown by ITcells is not perfect; consistent with some views beingbetter learned than others.– IT neurons can selectively learn arbitrary associationsbetween pairs of stimuli, a prerequisite for derivinginvariance from viewer-centered representations.– Consequently, because cell activity takes time todecay and because seeing different views of an objecttends to be clustered in time, the correlation(association) between several different retinotopicviews of the same object could be learned.
