Slow rates of approximation of U-statistics and V-statistics by quadratic forms of Gaussians

Kevin Han Huang, Peter Orbanz

We construct examples of degree-two U- and V-statistics of $n$ i.i.d.~heavy-tailed random vectors in $R^{d (n)}$ , whose $ν$ -th moments exist for $ν > 2$ , and provide tight…

Global optimality under amenable symmetry constraints

Peter Orbanz

Consider a convex function that is invariant under an group of transformations. If it has a minimizer, does it also have an invariant minimizer? Variants of this problem appear in…

Limit theorems for invariant distributions

Morgane Austern, Peter Orbanz

A distributional symmetry is invariance of a distribution under a group of transformations. Exchangeability and stationarity are examples. We explain that a result of ergodic theor…
