class skopt.space.transformers.LabelEncoder(X=None)[source][source]¶

LabelEncoder that can handle categorical variables.

Methods

fit(X)	Fit a list or array of categories.
inverse_transform(Xt)	Inverse transform integer categories back to their original
transform(X)	Transform an array of categories to a one-hot encoded representation.

__init__(X=None)[source][source]¶

Initialize self. See help(type(self)) for accurate signature.

fit(X)[source][source]¶
