Visualizing the relationships among multiple representations.
(A) Matrix of RDM correlations. Each entry compares two RDMs by Kendall's τA. The matrix is symmetric about a diagonal of ones. (B) MDS of the RDMs. Each point represents an RDM, and distances between the points approximate the τA correlation distances (1 minus τA) among the RDMs. The 2D distances are highly correlated (0.94, Pearson; 0.91, Spearman) with the RDM correlation distances. Visual inspection reveals that the group-average RDM is similar to the ground-truth RDM. However, the group-average RDM is also similar to some other model RDMs.
