Each dataset consists of an nxn confusion matrix, where rows indicate stimuli and columns indicate responses, and each value in the matrix indicates the empirical frequency for that stimulus–response pair.
In addition, model code for fitting a rate–distortion model to each of these confusion matrices is provided.
