Title:

CNNs meet real neurons: transfer learning and pattern selectivity in V4.<https://www.math.ethz.ch/sfs/news-and-events/research-seminar.html?s=fs17#e_10695>

Abstract:

Vision in humans and in non-human primates is mediated by a constellation of hierarchically organized visual areas. Visual cortex area V4, which has highly nonlinear response properties, is a challenging visual cortex area after V1 and V2 on the ventral pathway. We demonstrate that area V4 of the primate visual cortex can be accurately modeled via transfer learning of convolutional neural networks (CNNs). We also find that several different neural network architectures lead to similar predictive performance. This fact, combined with the high dimensionality of the models, makes model interpretation challenging. Hence, we introduce stability based principles to interpret these models and explain V4 neuron's pattern selectivity.
