Thank you for your reply.
But, I still have questions about the model selection section with K-fold cross validation…
“the average of the validation accuracies”
Does this mean Best valid acc or valid acc when stopped due to early stopping?
“The final model might be trained using the whole training data”
Does this mean that I need to train the entire training data only once, like a holdout, rather than k repeating train like KFold? Is there no need to k-split the train data in this part?
