Representational Dissimilarity Matrices (RDM) for multiclass invariant object categorization with plain background across different levels of variation, calculated based on models' features vector. Each element in a matrix shows the pairwise dissimilarities between the internal representations of a model for pairs of objects (see Materials and Methods). Each column in the figure shows the RDMs for a particular level of variation (from 0 to 6) and each row shows the RDMs of a model in different levels of variation. The first row illustrates the RDMs for human calculated based on responses in psychophysical experiments. The color bar at the top-right corner shows the degree of dissimilarity (measured as: 1-correlation— Spearman's rank correlation). The size of each matrix is 75^*75. For visualization, we selected a subset of responses to images in each category (15 images from each category).
