3. Suppose we run an online news aggregation platform which observes a person's habits of reading online news articles in order to recommend other articles the user might want to read. Suppose that we have characterised each online article by whether it mentions celebrity, whether it features sports, whether it features politics, and whether it features technology. Suppose we are given the examples below about whether a specific user reads various online articles. We want to use this data set to train a model that predicts which article this person would like to read based on the mentioned features (a) Suppose you would like to use decision tree learning for this task. Apply the TDIDT algorithm to learn a decision tree. Stop extending a branch of the decision tree when al remaining training examples have the same target feature. Demonstrate how you compute the information gain for ark:s) the features at each node. Draw the resulting decision tree
