Polynomial Features

Generate a new feature matrix consisting of all polynomial combinations of the features with less than a given degree

Documentation

Generate a new feature matrix consisting of all polynomial combinations of the features with less than a given degree

Configuration:

• degree

  The degree of the polynomial features.

• interaction_only

  If true, only interaction features are produced: features that are products of at most degree distinct input features (so not x ** 2, x * x ** 3, etc.).

• include_bias

  If True (default), then include a bias column, the feature in which all polynomial powers are zero (i.e. a column of ones - acts as an intercept term in a linear model).

Attributes:

• n_input_features_

• n_output_features_
