Witryna10 maj 2024 · Min-Max Scaler. The MinMaxScaler is the probably the most famous scaling algorithm, and follows the following formula for each feature: x i – m i n ( x) m a x ( x) – m i n ( x) It essentially shrinks the range such that the range is now between 0 and 1 (or -1 to 1 if there are negative values). This scaler works better for cases in which ... Witryna11 gru 2024 · The min-max approach (often called normalization) rescales the feature to a hard and fast range of [0,1] by subtracting the minimum value of the feature then dividing by the range.
