This functions runs information gain for a feature table and a class, returning the scores of information gain for all features
get_ig_for_feature_table_and_vector(feature_table, target_vector)
feature_table |
A table of features (observations in rows, variables in columns) |
target_vector |
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
