SklearnTransform

class SklearnTransform(in_column: Optional[Union[str, List[str]]], out_column: Optional[str], transformer: sklearn.base.TransformerMixin, inplace: bool = True, mode: Union[etna.transforms.math.sklearn.TransformMode, str] = 'per-segment')[source]

Bases: etna.transforms.base.Transform

Base class for different sklearn transforms.

Init SklearnTransform.

Parameters
  • in_column (Optional[Union[str, List[str]]]) – columns to be transformed, if None - all columns will be transformed.

  • transformer (sklearn.base.TransformerMixin) – sklearn.base.TransformerMixin instance.

  • inplace (bool) – features are changed by transformed.

  • out_column (Optional[str]) – base for the names of generated columns, uses self.__repr__() if not given.

  • mode (Union[etna.transforms.math.sklearn.TransformMode, str]) –

    “macro” or “per-segment”, way to transform features over segments.

    • If “macro”, transforms features globally, gluing the corresponding ones for all segments.

    • If “per-segment”, transforms features for each segment separately.

Raises

ValueError: – if incorrect mode given
