Consider splitting a parent node P into two child nodes, C1 and C2, using some attribute test condition. The composition of labeled training instances at every node is summarized in the Table below. Class 0 73 4 Class 1 303 (a) Calculate the Gini index and misclassification error rate of the parent node P. (b) Calculate the weighted Gini index of the child nodes. Would you consider this attribute test condition if Gini is used as the impurity measure? (c) Calculate the weighted misclassification rate of the child nodes. Would you consider this attribute test condition if misclassification rate is used as the impurity measure?
