Suppose you run k-means and after the algorithm converges, you have: C(1)=2,C(2)=2,C(3)=4, Which of the following statements are true? Check all that apply. Select one or more: a. The third example x(3) has been assigned to cluster 5 . b. The first and second training examples x(1) and x(2) have been assigned to the c. The second and third training examples have been assigned to the same cluster. d. Out of all the possible values of k{1,2,,K} the value K=3 minimizes x(2)k2
