Classification Using K Nearest Neighbors

























            As you will notice, the higher value of k results in a completed map with smoother
            boundaries. The actual complete map of Italy is here:
































            We can use this real completed map to calculate the percentage of the incorrectly classified
            points for the various values of k to determine the accuracy of the k-NN algorithm for
            different values of k:
