deephyper.skopt.space.space.StringEncoder

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

Bases: Transformer

StringEncoder transform.

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

Methods

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

fit(X)

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

Args: X : array-like, shape=(n_categories,)

List of categories.

inverse_transform(Xt)

Inverse transform string encoded categories back to their original representation.

Parameters:

Xt (array-like, shape=(n_samples,)) – String encoded categories.

Returns:

The original categories.

Return type:

X (array-like, shape=(n_samples,))

transform(X)

Transform an array of categories to a string encoded representation.

Parameters:

X (array-like, shape=(n_samples,)) – List of categories.

Returns:

The string encoded categories.

Return type:

Xt (array-like, shape=(n_samples,))
