Confusion matrix f score
WebI'm using Python and have some confusion matrixes. I'd like to calculate precisions and recalls and f-measure by confusion matrixes in multiclass classification. My result logs don't contain y_true and y_pred, just contain confusion matrix. Could you tell me how to get these scores from confusion matrix in multiclass classification? WebI want to compute the precision, recall and F1-score for my binary KerasClassifier model, but don't find any solution. ... And then I am predicting on new test data, and getting the confusion matrix like this: y_pred = model.predict(X_test) y_pred =(y_pred>0.5) list(y_pred) cm = confusion_matrix(Y_test, y_pred) print(cm)
