 ### Cross Validation
 To test the generalization performance of the trained network we'll use the testing samples provided to us to generate predictions and then analyze them compared to their ground-truth labels using a cross validation report. Note that we do not use any training data for cross validation because we want to test the model on samples it has never seen before.
