(Color online) Entropy decomposition for square matrices of (A) , (B) , and (C) (decimated), representing confusion matrices for a classification task at different accuracy levels as described by the right color bar.

<p>The interspersing of the plots representing matrices with different accuracies but similar entropies is evident at all levels for and but only for lower levels of accuracy for . This entails that accuracy is not a good criterion to judge the flow of information from the input labels to the output labels of a classifier (see text).
