Module features

Feature engineering techniques Feature engineering utilities

This module provides tools for feature engineering, which is the process of transforming raw data into features that better represent the underlying problem to predictive models.

Structs

PolynomialFeatures

Polynomial feature transformation

PowerTransformer

Optimized PowerTransformer for making data more Gaussian-like

Functions

binarize

Binarizes data (sets feature values to 0 or 1) according to a threshold

discretize_equal_frequency

Discretizes features using equal-frequency bins (quantiles)

discretize_equal_width

Discretizes features using equal-width bins

log_transform

Creates log-transformed features

power_transform

Applies various power transformations to make data more Gaussian-like
