WebApr 13, 2024 · Basic Syntax: confusion_matrix(y_test, y_pred, labels) To use this function, you just need. y_test: a list of the actual labels (the testing set); y_pred: a list of the predicted labels (you can see how we got these in the above code snippet).If you're not using a decision tree classifier, you can find analogous functions for that model. WebSep 21, 2024 · Input features and Output labels. In machine learning, we train our model on the train data and tune the hyper parameters(K for KNN)using the models performance on cross validation(CV) data.
