Self-attention in Vision Transformers Performs Perceptual Grouping, Not Attention
To answer this question, we revisited the attention formulation in these models and found that despite the name, computationally, these models perform a special class of relaxation labeling with similarity grouping effects.
Learning a model of shape selectivity in V4 cells reveals shape encoding mechanisms in the brain
We propose a hierarchical model that reveals V1/V2 encodings that are essential components for this transformation to the reported curvature representations in V4.
Multiplicative modulations in hue-selective cells enhance unique hue representation
Our simulation results indicate that multiplicative modulations have significant contributions in encoding of hues along intermediate directions in the MacLeod-Boynton diagram and that model V4 neurons have the capacity to encode unique hues.
Early recurrence enables figure border ownership
Various models proposed that feedback from higher ventral areas or lateral connections could provide the required contextual information.
Color-opponent mechanisms for local hue encoding in a hierarchical framework
A biologically plausible computational model for color representation is introduced.
