Author:

Class to reduce a given set of input classes into another set of output classes such that each class of the output set corresponds at least 1 (but potentially more) classes of the input set.

More formally, this class represents a map from m input classes to n output classes where \(m \geq n\).

See ClassTransformer.

Variables:

• output_class_names (list of str) – The list of names for the output (transformed) classes. For example [0] is the name of the first output class, i.e., that represented with index 0.

• class_groups (list of list of str) – A list which elements are lists of input class names defining the corresponding output class. For example, [1][4] is the fifth input class corresponding to the second output class.

static extract_ctransf_args(spec)

Parameters:

kwargs – The attributes for the ClassReducer

transform(y, out_prefix=None)

The fundamental transformation logic defining the class reducer.
