....have absolute value at most q(n; n 2; 2) This contradicts the fact that f has weight complexity at ) In the proof we have chosen ffi = 1=2 but any fixed value 0 ffi 1 is sufficient. The method of concentrating a distribution on a set of examples that is hard to be learned goes back to [ Pitt and Valiant, 1988 ] 4 Order identification From the result in the previous section we see that the requirement of producing large weights constitutes a serious obstacle for Perceptron like learning rules not only when exactly but also when PAC identifying Boolean threshold functions. In this section we try to ....

....positive or negative examples of the concept. We consider here two standard versions of this model: in one, the learner is required to produce as output a hypothesis belonging to the same class as the target concept, and in the other, the learner s hypotheses may be any polynomial time algorithm [64][50] 66] Several examples are known of concept classes that are hard to learn when hypotheses are restricted to belong to the same class as the target concept but easy to learn when they may belong to a larger class. In particular, Pitt and Valiant [64] showed that learning the class of k term ....
....may be any polynomial time algorithm [64] 50] 66] Several examples are known of concept classes that are hard to learn when hypotheses are restricted to belong to the same class as the target concept but easy to learn when they may belong to a larger class. In particular, Pitt and Valiant [64] showed that learning the class of k term DNF formulas (that is, functions that can be represented by a disjunction of k monomials) is NP hard if the learner is required to produce a k term DNF formula, but is easy if the learner may use a representation of k CNF formulas. In this chapter, we show ....
