Consider the data points: P1(3, 10), P2(4, 4), P3(4, 8), P4(4, 6), P5(6, 4), P6(6, 10). One run of a 2- means algorithm clusters P1, P2, and P3 into one cluster and P4, P5, and P6 into the second cluster. Another run of the 2-means algorithm puts P1, P3, and P6 into one cluster and P2, P4, and P5 into another cluster a. (10) For each clustering compute the sum of squared errors. Which clustering is a better clustering based on their SSE values? b. (10) Compute the Rand index to compares the two clusterings
