skopt.space.transformers.StringEncoder

class skopt.space.transformers.StringEncoder(dtype=<class 'str'>)

StringEncoder transform.

The transform will cast everything to a string and the inverse transform will cast to the type defined in dtype.

Methods

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

__init__(dtype=<class 'str'>)

fit(X)

Fit a list or array of categories. All elements must be from the same type.

Parameters:

Xarray-like, shape=(n_categories,)

List of categories.

inverse_transform(Xt)

Inverse transform string encoded categories back to their original representation.

Parameters:

Xtarray-like, shape=(n_samples,)

String encoded categories.

Returns:

Xarray-like, shape=(n_samples,)

The original categories.

transform(X)

Transform an array of categories to a string encoded representation.

Parameters:

Xarray-like, shape=(n_samples,)

List of categories.

Returns:

Xtarray-like, shape=(n_samples,)

The string encoded categories.
