WebMay 26, 2024 · Even though sklearn’s train_test_split method is using a stratified split, which means that the train and test set have the same distribution of the target variable, it’s possible that you accidentally train on a subset which doesn’t reflect the real world. WebHere, we split the input data ( X/y) into training data ( X_train; y_train) and testing data ( X_test; y_test) using a test_size=0.20, meaning that 20% of our data will be used for testing. In other words, we're creating a 80/20 split. Shuffling (i.e. randomly drawing) samples is applied as part of the fit.
