This estimator scales and translates each feature individually such that the maximal absolute value of each feature in the training set will be 1.0. It does not shift/center the data, and thus does not destroy any sparsity. WebLet us scale all the features to the same scale and a range from 0 to 1 in values using sklearn MinMaxScaler below: from sklearn.preprocessing import MinMaxScaler. X_copy = X.copy() #We create a copy so we can still refer to the original dataframe later. scaler = MinMaxScaler() X_columns = X.columns. shoreline houses for rent zillow
