Hi, I am working of classifiers. My problem is as follow:
train_labels = Nx1; train_data = NxD;
test_ labels = Mx1; test_data = MxD;
where, M>>N;
I am using Knn classifier and I have to find the classification accuracy by k-fold cross-validation. Any help?

which is helpful for identify the optimal K value and avoid overfitting, underfitting issues

This example illustrates k-fold cross validation for knn classification:
However, you ordinarily wouldn't divide your data into train/test sets if you were going to use cross-validation.
