Encodes values in a column through a variety of methods:

Label Encoding: Encode target labels with value between 0 and n_classes-1. See scikit-learn's for full documentation.

Target Encoding: Encode a categorical column with the average value of a target column for the corresponding value of the categorical column. See scikit-learn's for full documentation.

One Hot Encoding: Encode a categorical column as a 0 or 1 for each possible category, each of which will be it's own row.

Parameters

Name
Type
Description
Is Optional
