Suppose we have a learning algorithm that is guaranteed with high probability to be slightly better than random guessing – we call this a . weak learner. E.g. if an email contains the work “money” then classify it as spam, otherwise as non-spam. Reading. Ch. 18.6-18.12, 20.1-20.3.2. (Not Ch. 18.5). Outline. Different types of learning problems.
