Questiоn 6 (12 pоints) Yоu аre strаnded on а deserted island. Mushrooms of various types grow widely all over the island, but no other food is anywhere to be found. Some of the mushrooms have been determined as poisonous and others as not (determined by your former companions’ trial and error). You are the only one remaining on the island. You have the following data to consider: Example : Not Heavy : Smelly : Spotted : Smooth : Edible A 1 0 0 0 1 B 1 0 1 0 1 C 1 1 1 0 0 D 0 1 0 0 0 E 0 1 0 1 1 F 0 0 0 1 0 G 1 0 1 1 0 H 1 0 0 1 0 Example : Not Heavy : Smelly : Spotty : Smooth : Edible U 0 1 1 1 ? V 1 1 0 1 ? W 1 1 0 0 ? You know whether or not mushrooms A through H are poisonous, but you do not know about U, V and W. (2 points) Consider only mushrooms A through H. Compute the entropy impurity measure for the parent node? (3 points) Given that you are using feature (smoothness) to split the parent node, calculate its information gain using entropy as the impurity measure. Then, illustrate the resulting decision tree split along with the leaf nodes, including sample counts. (4 points) Finalize the decision tree to classify mushrooms as edible or not, and depict it. (You are not required to do any calculations to answer this question.) (3 points) Classify mushrooms U, V and W using the decision tree from part (3).
