Скачать или смотреть Understanding Target Encoding for Categorical Features

Welcome to the seventeenth video of the series "Build your First Machine Learning Project". In this we'll see Target Encoding aka Mean Encoding.

Target encoding is the process of replacing a categorical value with the mean of the target variable. Any non-categorical columns are automatically dropped by the target encoder model.

Let's understand it in deep.
