Web8 Sep 2024 · How to Calculate F1 Score in Python (Including Example) When using classification models in machine learning, a common metric that we use to assess the quality of the model is the F1 Score. This metric is calculated as: F1 Score = 2 * (Precision * Recall) / (Precision + Recall) where: Webscore – \(R^2\) of self.predict(X) w.r.t. y. Return type: float. Notes. The \(R^2\) score used when calling score on a regressor uses multioutput='uniform_average' from version 0.23 to keep consistent with default value of r2_score().
