Webb15 dec. 2024 · Hello I've gotten to the neural network part of supervised machine learning, and there is a slight problem with the classification, using MLPClassifier and mglearn.plots.plot_2d_seperator. On page 110, it says X, y = make_moons(n_samples... Webb# use THE SAME transformation on the test set, # using min and range of the training set. See Chapter 3 (unsupervised learning) for details.
