cross validation

Post by liid » Mon Dec 24, 2018 5:31 am

Is there a possibility to view the individual results of each fold of a K-fold CV?
Also, how is the final result for K-fold CV calculated? average of K folds? min of the K folds? max of the K folds?

Thanks

No, that's not possible.

We create a single confusion matrix over all folds (because each record in the dataset is used for evaluation once), which is used to calculate accuracy.
