WebIn this expository note, we give a modern proof of Hanson-Wright inequality for quadratic forms in sub-gaussian random variables.We deduce a useful concentration inequality for sub-gaussian random vectors.Two examples are given to illustrate these results: a concentration of distances between random vectors and subspaces, and a bound on the … WebHanson-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 the original weak point.
