Information, Prediction, and Query by Committee

Neural Information Processing Systems

We analyze the "query by committee" algorithm, a method for filtering informativequeries from a random stream of inputs. We show that if the two-member committee algorithm achieves information gainwith positive lower bound, then the prediction error decreases exponentially with the number of queries. We show that, in particular, this exponential decrease holds for query learning of thresholded smooth functions.







Estimating Average-Case Learning Curves Using Bayesian, Statistical Physics and VC Dimension Methods

Neural Information Processing Systems

In this paper we investigate an average-case model of concept learning, and give results that place the popular statistical physics and VC dimension theories of learning curve behavior in a common framework.
