Hanson wright不等式
Web1. Hanson-Wrightinequality Hanson-Wright inequality is a general concentration result for quadratic forms in sub-gaussian random variables. A version of this theorem was first proved in [9, 19], however with one weak point mentioned in Remark 1.2. In this article we give a modern proof of Hanson-Wright inequality, which automatically fixes ... WebView the profiles of people named Hanson Wright.

Web熵方法是研究集中不等式的一类重要方法，而在正式导出之前，需要引入熵与信息论的一些定义与工具。 Shannon熵： H(X)=\bm{E}[-\log p(X)]=-\sum \limits_{x \in \mathcal{X}} p(x)\log p(x) \\ 。 Shannon熵非负且凹，可将其理解为对分布复杂度及随机事件所包含信息的度量，当一个分布比较复杂（如它是若干子分布的 ...

Webcombines a chaining argument with the classical (nonuniform) Hanson-Wright inequality. In a typical application, the dimension K will be small (in Section 4, we use Theorem 1 with K - 1) and m, d may be large. A uniform Hanson-Wright inequality, with a similar upper bound, is also given in Adamczak (2015).
