Understanding cross_val_score() and its Connection to Memory Issues Overview of cross_val_score() cross_val_score() is a function from scikit-learn’s model_selection module that performs k-fold cross-validation on a trained model. It allows us to evaluate the performance of a machine learning model on unseen data by splitting it into training and testing sets multiple times, with each split used as a separate test set. In the context of our problem, we are using cross_val_score() to estimate the accuracy of a Bagging kNN classifier.
