Borja Rodríguez-Gálvez, Ragnar Thobaben, Mikael Skoglund

TL;DR该论文提出了一种新的高概率PAC-Bayes界限，其中涉及到了带界范围和更一般尾部行为的损失，并提出了一些新的基于参数和基于事件的界限技术，可以得到更紧密和可解释的结果，并将结果扩展到任何现有范围上

Abstract

In this paper, we present new high-probability pac-bayes bounds for different types of losses. Firstly, for losses with a bounded range, w
