A developer scales features before cross-validation, then tunes a classifier. Which implementation pattern is safer?

Choose the Best Answer

Fit a separate scaler on each validation fold and compare it with unscaled training data. Put scaling and the classifier inside a pipeline used by the cross-validation tool. Tune the classifier outside preprocessing, then manually copy the best parameters into a script. Fit the scaler on the full dataset once, then reuse those scaled values in every fold.
