1. In this problem we have circles of three different colors and we want to classify a new circle (indicated in black) as one of these colors. The red, blue and green circles are illustrated below along with an unknown circle which we want to classify. (a) Classify the unknown circle as red, green or blue using a single nearest neighbor. (b) If possible, uniquely classify the unknown circle as red, green or blue using kNN with k-2. Justify your answer; if you are unable to uniquely classify it, explain why. (c) If possible, uniquely classify the unknown circle as red, green or blue using kNN with k-3. Justify your answer; if you are unable to uniquely classify it, explain why
