....for a particular convex combination of hypotheses the complexity term necessarily depends on the complexity of the most complex hypothesis, even if this hypothesis has a low voting weight and hence little effect on the combined hypothesis. Golea et al. present a generalization of this result in [5] where the bound on generalization error depends on the margin and on a complexity term which involves the average VC dimension of the class of base hypotheses (where the average is in term of the weights assigned to the base hypotheses in the convex combination) In Section 3 of this paper we ....
....is in terms of the weights assigned to the hidden units and the complexity of an individual hidden unit is in terms of the proportion of training examples which are classified near threshold) This is accomplished by considering the network as a thresholded convex combination of hidden units. In [5] Golea et al. bound the generalization error of a binary decision tree in terms of the margin and a complexity term by considering a binary decision tree as a thresholded convex combination of leaf functions. Their complexity term depends on the VC dimension of the class of node decision ....
