RISK THEORY-COLLECTIVE RISK MODEL Example Consider an insurance portfolio whereby the aggregate claims S has a compound Poisson distribution with \lambda =5 and the claim amount will be 1 or 2 with probabilities (2)/(3) and (1)/(3), respectively. Calculate f_(S)(x) and F_(S)(x) for x=0,1,2,dots,6 (use alternative method). Calculate E(S) and Var(S) Given relative security loading =150%, calculate the premium, G Calculate the expected stop-loss reinsurance claims when deductible is 4. The insurer agrees to pay dividend equal to the excess of 80% of the premium over the claims. Calculate G-E(S)-E(D). E(D)=2.1569

(c) (2 points) To find an appropriate learning rate \alpha, you tried \alpha = 0.01, 0.1, 1 and 10. For each choice of \alpha, you plot J(\theta) versus number of iterations as shown in Figure 1(b). (The figure is colored. Please read the PDF file if you print out in black/white) However, you forget to record which line corresponds to which \alpha. Based on the plot, the red line is most likely from which \alpha? ?. 0.01 B. 0.1 C. 1 D. 10 (d) (2 points) Which of the following statements about K-Means is correct? A. To choose a good K, we can run K-Means multiple times with different choices of K, the run with smaller cohesiveness score must be better. B. Once the centroids of two consecutive iterations don't change, K-Means algorithm has converged. C. K-Means will always give the same results regardless of the initialization of the centroids.
