In this problem you will implement the classier d A=ar max lo 51" Ar\". 1 y chem?\" g kwe} () The log does not change the maximizer since it is a strictly increasing function. Here and throught out the course, logarithms are natural unless a different base is specied. (a) Intuitively, pk, is the probability that feature 5." appears once in a class-k document. What additional assumption about the data, in addition to the naive Bayes assumption, makes this intuition valid? (b) By applying properties of the natural logarithm, simplify the expression on the right- hand side of (1), substituting the formula for if\". Your nal expression should not contain logs of products or divisors
