It gives us a snapshot of the training process and the direction in which the network learns. An awesome explanation is from Andrej Karpathy at Stanford University at this link. And this section is heavily inspired by it.
WebMar 8, 2024 · So in this case, we can use something as. cross_val_score (my model, X, y, cv=5) This is what normally is done, with a score based on the mean of the 5-fold test-set. But as we know the DecisionTree or what ever model y like, it has some hyper parameters. The smart approach seems to be GridSearchCV to find these hyper parameters.
