.This functions runs information gain for a feature table and a class, returning the scores of information gain for all features
SU(x, y, base = 2) IG(x, y, base = 2) get_su(x, y) get_ig(x, y)
x |
A table of features (observations in rows, variables in columns) |
y |
A target vector, factor containing classes of the observations. Note: the observations must be in the same order as the parameter x. |
A dataframe containing the SU values for each feature
