WebApr 19, 2024 · The PAC-Bayes bound for TSVMs has exactly the same form as the PAC-Bayes bound for SVMs. Except for the above work, we also proposed prior PAC-Bayes … WebAs a result, the theoretical sections are quite difficult to follow. It is not clear to me how the information bounds are used, it seems that instead of these bounds the authors end up focusing on KL-based bounds which are more reminiscent of PAC-Bayes. For the experimental results, the improvement over non-data-dependent bounds is to be expected. cost of reupholstering sofa

Web3 PAC-Bayes Bounds Our PAC-Bayes proofs are based on a martingale technique due to Lever et al. [10] and Seldin et al. [17]. The so-called “one-sided” bounds we present, while not as tight as some “two-sided” bounds, are arguably more interpretable, and are easily obtained using martingale-based concentration in-equalities.
