Which accuracy score are you using? If it is proportion correctly classified, that is a misleading improper scoring rule. Frank rkok wrote
I am using machine learning for one researching. I am using some classifiers with 5-fold CV . I would like to know how it is possible to extract the accuracy, for example, for KNN,neural networks and J48, for each one of 5-fold because when I apply CV to my classifier, I obtain the "mean accuracy" of 5-fold but each accuracy/error of each fold is not returned. Any help is welcome and grateful. Thanks in advance! Regards!!
