Basically, we're indicating whether a certain item of a particular category was present or not. This is done by creating new rows for each entry in the data and columns representing their categories.

WebEncode categorical features as a one-hot numeric array. The input to this transformer should be an array-like of integers or strings, denoting the values taken on by categorical (discrete) features. The features are encoded using a one-hot (aka ‘one-of-K’ or ‘dummy’) encoding scheme. Web24. feb 2024. · In python, one-hot encoding is a technique used a convert categorical data into numbers so that you can use it for machine learning algorithms.
