I'm trying to figure out how to produce a confusion matrix with cross_validate. I'm able to print out the scores with the code I have so far. # Instantiating model model = DecisionTreeClassifier() #Scores scoring = {'accuracy' : make_scorer(accuracy_score), 'precision' : make_scorer(precision_score), 'recall' : make_scorer(recall_score), 'f1_score' : make_scorer(f1_score)} # 10-fold cross validation scores = cross_validate(model, X, y, cv=10, scoring=scoring) print("Accuracy (Testing): %0.2f (+/- %0.2f)" % (scores['test_accuracy'].mean(), scores['test_accuracy'].std() * 2)) print("Precision (Testing): %0.2f (+/- %0.2f)" % (scores['test_precision'].mean(), scores['test_precision'].std() * 2)) print("Recall (Testing): %0.2f (+/- %0.2f)" % (scores['test_recall'].mean(), scores['test_recall'].std() * 2)) print("F1-Score (Testing): %0.2f (+/- %0.2f)" % (scores['test_f1_score'].mean(), scores['test_f1_score'].std() * 2)) But I'm trying to get that data into a confusion matrix. I'm able to make a confusion matrix by using cross_val_predict - y_train_pred = cross_val_predict(model, X, y, cv=10) confusion_matrix(y, y_train_pred) Which is great, but since it's doing it's own cross validation, the results won't match up. I'm just looking for a way to produce both with matching results. Continue reading...
