Abstract

Given N learners each capable of learning concepts (subsets) of a domain set X in the sense of Valiant [19], we are interested in obtaining a composite system constituted by the fuser and the individual learners. We consider two cases: open and closed fusion. In open fusion the fuser is given the sample and the hypotheses of the individual learners; we show that the fusion rule can be obtained by formulating this problem as another learning problem. For the case all individual learners are trained with the same sample, we show sufficiency conditions that ensure the composite system to be better than the best of the individual. Second, in closed fusion the fuser does not have an access to either the training sample or the hypotheses of the individual learners. By suitably designing a linear threshold function of the outputs of individual learners, we show that the composite system can be made better than the best of the learners.
