dtoolkit.transformer.OneHotEncoder.transform#

OneHotEncoder.transform(X: TwoDimArray) → TwoDimArray | csr_matrix[source]#

Transform X using one-hot encoding.

If there are infrequent categories for a feature, the infrequent categories will be grouped into a single category.

Parameters

Xarray-like of shape (n_samples, n_features): The data to encode.

Returns

X_out{ndarray, sparse matrix} of shape (n_samples, n_encoded_features): Transformed input. If sparse_output=True, a sparse matrix will be returned.

Notes

This would let DataFrame out.
