WebJun 30, 2024 · 2. Scale the Dataset. Next, we can scale the dataset. We will use the MinMaxScaler to scale each input variable to the range [0, 1]. The best practice use of this scaler is to fit it on the training dataset and then apply the transform to the training dataset, and other datasets: in this case, the test dataset. WebMay 10, 2024 · Robust Scaler The RobustScaler uses a similar method to the Min-Max scaler but it instead uses the interquartile range, rathar than the min-max, so that it is robust to outliers. Therefore it follows the formula: x i – Q 1 ( x) Q 3 ( x) – Q 1 ( x) For each feature.
