WebMar 22, 2024 · Never fit scaler again on the test data Sklearn has following four scalers primarily 1. Minmax scaler 2. Robust scaler 3. Standard Scaler 4. Normalizer. Minmax scaler should be the first choice for scaling. WebMay 9, 2024 · RobustScaler does not remove outliers. When fitted, it computes a scale and mean that's robust to outliers. Outliers however would later be transformed like all other points using those parameters. In other words, RobustScaler preserves outliers and tries to not let them influence the scaling of the non-outliers. This Scaler removes the median ...
