WebMutual Information (MI) will be calculated for each pair of signals (unless the "Avoid related pairs" option is checked; see "Options" below). In addition to MI, you will see the following quantities (where 'N' stands for normalized):

WebNormalized Mutual Information (NMI) is a normalization of the Mutual Information (MI) score to scale the results between 0 (no mutual information) and 1 (perfect correlation). In this function, mutual information is normalized by some generalized mean of H(labels_true) and H(labels_pred)), See wiki. Skip RI, ARI for complexity.
