normalized mutual information python

Mutual information is used in determining the similarity of two different clusterings of a dataset. Example 1 Entropy The … MI is used to quantify both the relevance and the redundancy. Find normalized mutual information of two covers of a network G(V, E) where each cover has |V| lines, each having the node label and the corresponding community label and finds the normalized … Releae Note. It is can be shown that around the optimal variance, the mutual information estimate is relatively insensitive to small changes of the standard deviation.
