Margin Distribution Bounds on Generalization - ePrints Soton

WebUsing standard results in the literature, we can obtain both generalization bounds (a la [Bartlett and Mendelson, 2002]) and margin bounds (a la Koltchinskii and Panchenko [2002]). A staggering number of results have focused on this problem in varied special cases. Perhaps the most extensively studied are margin bounds for the 0-1 loss. For L Web8 A Margin Bound We can use the PAC-Bayesian theorem to prove a generalization bound for a variant of L probit-L 2 regression, also known as probit regression. We take the prior to be the multivariant Gaussian N(0,I) and we consider a family of posteriors Q w where each posterior is defined by a weight vector w. P = N(0,I) (8) Q w = N(w,I) (9) defining enum in interface c# https://htctrust.com

Webone in the L´evy distance. Namely, we proved that the empirical margin distribution converges to the true margin distribution with probability 1 uniformly over the class G of classifiers if and only if the class G is Glivenko-Cantelli. Moreover, if G is a Donsker class, then the rate of convergence in L´evy distance is O(n −1/4).
