Functions

`binary_unique_value_features()`	A feature factory function for binary variables
`create_features_all_unique_values()`	A simple feature factory function for variables that take a (small) number of unique values
`create_features_split_regular_bins()`	A feature factory function creating features splitting the variable’s range into equally sized bins
`create_features_split_regular_ge()`	A feature factory function creating bipartitions splitting the dataset at equidistant thresholds between minimum and maximum the variable’s range
