sklearn.metrics.accuracy_score¶ sklearn.metrics. accuracy_score (y_true, y_pred, *, normalize = True, sample_weight = None) [source] ¶ Accuracy classification score. In multilabel classification, this function computes subset accuracy: the set of labels predicted for a sample must exactly match the corresponding set of labels in y_true..

26.04.2017 · Accuracy is probably not what you want for Multi-Label classification especially if your classes are unbalanced. Let’s say you have a class A present for 90% of your dataset, and classes B and C that occurs about 10% of the time, a model that always return class A and never class B and C will have 70% accuracy but no predictive power.

01.10.2021 · F1 Score = 2* Precision Score * Recall Score/ (Precision Score + Recall Score/) The accuracy score from above confusion matrix will come out to be the following: F1 score = (2 * 0.972 * 0.972) / (0.972 + 0.972) = 1.89 / 1.944 = 0.972. The same score can be obtained by using f1_score method from sklearn.metrics
