A decision tree classifier needs to be designed to determine whether a person is going to buy a computer based on several attributes. The table of training set is given below. This problem is parameterized as follows. [ (a) Calculate the entropy of the entire population. (b) If Parameter1 is chosen at the root node, calculate the information gain. (c) Calculate the Gini Index of Parameter1. (d) Suppose "Age" is chosen at the root node, and then "Income" is chosen as the next attribute. Draw the decision space
