2. Nearest Neighbor 1We train a 3-Nearest Neighbor model on a dataset. If we test it on the exact same dataset, will our model always give perfect results (i.e., 0 error). Briefly explain. 2. What is the leave-one-out cross validation error for the following dataset us- ing a) 1 nearest neighbor b) 3 nearest neighbor (you can break ties randomly) Feature Class 10 2.
