Calculates the mutual information matrix — rs_mutual_info • bixverse

Calculates the pairwise mutual information across all columns in the data.

Usage

rs_mutual_info(x, n_bins, strategy, normalise)

Arguments

x: R matrix with doubles for which to calculate the mutual information
n_bins: Optional integer. Number of bins to use. If NULL is provided the function will default to sqrt(nrow(x)).
strategy: String. Binning strategy. One of c("equal_width", "equal_freq"). Unknown strings default to "equal_width".
normalise: Boolean. Shall the normalised mutual information be calculated via joint entropy.

Value

The symmetric mutual information matrix. The diagonal holds the column entropies, or 0 if normalise = TRUE.
