1. Suppose that the probability of five events are P(1) = 0.5, and P(2) = P(3) = P(4)= P(5) = 0.125. Calculate the entropy. Explain in words what this means. 2. Three binary nodes, N1, N2, and N3, split examples into (0, 6), (1,5), and (3,3), respectively. For each node, calculate its entropy, Gini impurity, and classifica- tion error. 1.
