新的动态Haussler引理为实值类提供了精确界限

本文介绍了Haussler覆盖引理的一个精确全局动态类似物,将其扩展到在归一化 $\ell_p$ 距离下(对于 $1 \le p < \infty$)的有界实值类。该研究提供了一个与实例序列无关的全局动态覆盖界限,并为二元类提供了匹配的最坏情况下界。证明方法结合了降秩校正计划、精确采样前缀和精确续接,并利用共享父路由来优化这些续接。 AI

    一个尖锐的动态 Haussler 引理

    arXiv:2610.29898v1 Announce Type: new Abstract: Haussler's covering lemma (JCTA 1995) gives the sharp $(C/\delta)^d$ metric-entropy bound for binary VC classes under normalized $\ell_1$ distance. We prove a sharp global dynamic analogue for bounded real-valued classes in normaliz…
