class ValueOneHotEncoder(ignore_unknown=True)

Bases: object

A simple one-hot encoder, which encodes individual values. A one-hot encoder transforms a categorical input value into an array whose length is the number of categories where all values are zero except one whose value is one, indicating the category that is active.

Parameters:

ignore_unknown – whether unknown input values (not seen during fit) shall be ignored, resulting in an array of zeroes; if False, throw an exception instead

fit(values: Sequence[Any])

transform(value) → ndarray
