Shuffling the training set
Weblevel 1. · 1y. If your dataset has already been split into a training set and a test set, you shuffling them does not have any impact on the model 'memorizing' versus 'learning'. This is because the shuffling only changes the order in which examples in the training set are processed to fit the model. This is the case with the test set as well.
