pyreal.transformers.MappingsOneHotEncoder

class pyreal.transformers.MappingsOneHotEncoder(mappings, **kwargs)

Converts data from categorical form to one-hot-encoded, with feature names based on a mappings object which includes two dictionaries

__init__(mappings, **kwargs)

Initialize the transformer

Parameters:

mappings (Mappings) – Mappings from categorical column names to one-hot-encoded

Methods

__init__(mappings, **kwargs)	Initialize the transformer
data_transform(x)	One-hot encode x.
fit(x, **params)	Fit this transformer to data
fit_transform(x, **fit_params)	Fits this transformer to data and then transforms the same data
inverse_data_transform(x_onehot)	Transforms one-hot encoded data x_onehot back into categorical form.
inverse_transform(x_new)	Transforms data x_new from new feature space back into the original feature space.
