Dataset Preprocessing

Clean and transform data before analysis or machine learning.

Class Labeling

Create classification targets from numeric or categorical columns.

Labeling Methods

Binary threshold: values below the threshold become Class_0 and the rest become Class_1.

Quantile: numeric data is automatically divided into 2–10 relatively balanced classes.

Copy category: categorical values in the source column are used directly as classification labels.
