Consider the following data points (P1 to P7) with two features, x1 and x2. Labels for P1 to P5 have been given. a) Classify (assign labels) to the remaining points using KNN with k=1 using L1 distance. P1 P2 P3 P4 P5 P6 P7 x1 0 2 0 -1 1 0 5 x2 0 2 4 1 2 -4 1 Label 1 2 312 b) Can you use k=2 or k=3? Briefly explain your answer. c) What are the advantages and disadvantages of using a large value of 'k' in KNN? Explain briefly.
