Using the dataset above, calculate the mutual information for each feature (X1, X2, X3) to determine the root node for a Decision Tree trained on the above data. 110 • What is I(Y:X;)? • What is I(Y; X2)? 0.061 . What is I(Y; X;)? 0.311 • What feature should be split on at the root node? 2. Calculate what the next split should be. 3. Draw the resulting tree.
