Webbased generalization bound. Bartlett et al. [7] use a scale-sensitive measure of complexity to establish a generalization bound. They derive a margin-normalized spectral complex-ity, i.e., the product of spectral norms of weight matrices divided by the margin, via covering number approximation of Rademacher complexity; they further show empirically WebGeneralization Bounds By Stability Stability The basic idea of stability is that a good algorithm should not change its solution much if we modify the training set slightly. We …

Because learning algorithms are evaluated on finite samples, the evaluation of a learning algorithm may be sensitive to sampling error. As a result, measurements of prediction error on the current data ma… ein number without a business

WebCovering Number Bounds. Based on the ‘ 1-norm covering number bound of linear operators, Guermeur [9] obtained a generalization bound exhibiting a linear dependence on the class size, which was improved by [37] to a radical dependence. Hill and Doucet [11] derived a class-size independent risk guarantee. WebDec 8, 2024 · What if we want to find the generalization error?
