b) Assume that you are given the set of labeled training examples below, where each attribute has three possible values X, Y, or Z. You choose to learn a decision tree and select "0" as the default output if there are ties. Example A1 A2 A3 Output X X # 1 X 1 #2 Y Y X 1 # 3 X Y X 1 #4 Y X Z 1 X X Z 0 Y Y Y X Y Y 0 Y Y Y 0 Which attribute would choose as the root of the tree? Support your answer with the information gain theory. [8 marks] c) Draw the decision tree using the result(s) from 2(b). Based on the decision tree, what will be the output for a new Example #9 if A1=X, A2=Y A3=Z? [7 marks] d) If all attributes in example (b) are binary, what is the maximum number of decision trees that we can have for this data? [2 marks] # 5 #6 #7 #8 0
