4 Decision tree: 4-1 In order to compare different classification models, you decide to use the decision tree approach Provide the Entropy of Y: Entropy(Y). 4-2 Which variable (X, or X,) can be used for the first node of your decision tree? Provide your justification, based on the Entropy criteria 5. Rayes model: You decide to use Bayes classification model taking into account Y, X, and X, Provide the probability of Y- "Strong" for a new observation with: X, = "12" X3 = 'No"
