WebApr 12, 2024 · It probably is fairly rare to need to use fit and not instead fit_transform for a sklearn transformer. It nevertheless makes sense to keep the method separate: fitting a transformer is learning relevant information about the data, while transforming produces an altered dataset. WebJun 28, 2024 · fit computes the mean and std to be used for later scaling. (jsut a computation), nothing is given to you. transform uses a previously computed mean and std to autoscale the data (subtract mean from all values and then divide it by std). fit_transform does both at the same time. So you can do it with 1 line of code instead of 2. WebFor the same reason, fit_predict, fit_transform, score and partial_fit methods need to accept a y argument in the second place if they are implemented. The method should return the object (self).
