public final class Ms_mutinfo extends Object
Mutual information for discrete variables.

Computes mutual information I(X,Y) = H(X) + H(Y) - H(X,Y) measuring the amount of information obtained about one variable through observing the other. Fundamental measure in feature selection, clustering validation, and dependency analysis.

      public static double ms_mutinfo(Matrix x, Matrix y)
      Compute mutual information I(x,y) of two discrete variables x and y.
      Parameters:
      x - first matrix
      y - second matrix of the same length
      Returns:
      mutual information z=I(x,y)
