WebWe derive a dimension-free Hanson–Wright inequality for quadratic forms of independent sub-gaussian random variables in a separable Hilbert space. Our inequality is an infinite-dimensional generalization of the classical Hanson–Wright inequality for finite-dimensional Euclidean random vectors.

In particular, for ...
WebThere are inequalities similar to (1.3) for multilinear chaos in Gaussian random variables proven in [22] (and in fact, a lower bound using the same quantities as well), and in [4] for polynomials in sub-Gaussian random variables. Moreover, extensions of the Hanson–Wright inequality to certain types of dependent random variables have been
