We analyze a hierarchy of upper bounds proposed by Lasserre in [SIAM J. Optim. 21(3) (2011), pp. 864--885], obtained by searching for an optimal probability density function h on K which is a sum of squares of polynomials, so that the expectation $\\int_{K}f(x)h(x)dx$ is minimized. We show that the rate of convergence is $O(1/\\sqrt{r})$, where 2r is the degree bound on the density function. This analysis applies to the case when f is Lipschitz continuous and K is a full-dimensional compact set satisfying some boundary condition (which is satisfied, e.g., for polytopes and the Euclidean ball). The r-th upper bound in the hierarchy may be computed using semidefinite programming if f is a polynomial of degree d, and if all moments of order up to 2r+d of the Lebesgue measure on K are known, which holds for example if K is a simplex, hypercube, or a Euclidean ball.", "revisions": [ { "version": "v1", "updated": "2014-11-25T13:44:21.000Z" } ], "analyses": { "subjects": [ "90C22", "90C26", "90C30" ], "keywords": [ "lasserres measure-based hierarchy", "polynomial optimization", "convergence analysis", "optimal probability density function", "euclidean ball" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1411.6867D" } } }
