Chernoff-Hoeffding Inequality - University of Utah

網頁2024年4月10日 · We use two concentration bounds, the first of which is known as the Chernoff Bound. The original statement can be found in [3], we use the version which can be found in chapter 5 of [26]. The Chernoff Bound. For any t ... 網頁Chernoff bound P(X-EX \geq t) \leq \inf_{\lambda \geq 0} E[e^{\lambda(X-EX)}]e^{-\lambda t} 我们发现, 这个上界随着 t 增长衰减的速率取决于矩母函数的上界, 这启发我们, 如果一个 … basil summer

網頁2024年12月7日 · Chernoff bounds Chernoff 界并不单指某一个不等式，它指一系列用指数衰减的值来限定尾概率的方法，在推导的过程中会大量使用矩母函数。 The Chernoff bound is like a genericized trademark: it refers not to a particular inequality, but rather a technique for obtaining exponentially decreasing bounds on tail probabilities. 網頁APPLICATIONS OF CHERNOFF BOUNDS 5 Hence, the ideal choice of tfor our bound is ln(1 + ). Substituting this value into our expression, we nd that Pr(X (1 + ) ) (e (1+ )(1+ )) This bound is quite cumbersome to use, so it is useful to provide a slightly less unwieldy 網頁本文使用 Zhihu On VSCode 创作并发布今天介绍一个在算法分析以及机器学习中比较常用的技术，Chernoff界。这个技术主要是用来衡量尾概率，即如果样本值偏离期望，那么偏 … tacos lopez tijuana style west jordan menu
