(5) (10 points) Almost every algorithm in the online mistake bound model in this course (Winnow, Perceptron, decision list, etc) updates its hypothesis only after making a mistake. If the algorithm doesn't make a mistake, its hypothesis is not updated. We want to show this behaviour holds without loss of generality: Suppose some deterninistic algorithm A learns a concept class C in the Online Learning model making at most M mistakes, and A may change its hypothesis even when not making a mistake. Show how to modify A to get a deterministic algorithm B that only updates its hypothesis after a mistake, and B still makes at most M mistakes
