Webb5 nov. 2024 · MinMax Scaler is one of the most popular scaling algorithms. It transforms features by scaling each feature to a given range, which is generally [0,1], or [-1,-1] in case of negative values. For each feature, the MinMax Scaler follows the formula: Webb28 maj 2024 · Another way to normalize the input features/variables (apart from the standardization that scales the features so that they have μ=0and σ=1) is the Min-Max scaler. By doing so, all features will be transformed into the range [0,1] meaning that the minimum and maximum value of a feature / variable is going to be 0 and 1 , respectively.
