Witryna20 lut 2024 · After completing the data preprocessing. it’s time to implement machine learning algorithm on it. We are going to use sklearn’s GaussianNB module. clf = GaussianNB () clf.fit (features_train, target_train) target_pred = clf.predict (features_test) We have built a GaussianNB classifier. The classifier is trained using training data.
