The reason for normalization is so that no feature overly dominates the gradient of the loss function. Some algorithms are better at dealing with unnormalized features than others, I think, but in general if your features have vastly different scales you could get in trouble. So normalizing to the range 0 - 1 is sensible. Web3 de fev. de 2024 · MinMax Scaler shrinks the data within the given range, usually of 0 to 1. It transforms data by scaling features to a given range. It scales the values to a specific value range without changing the shape of the original distribution.
