On the inability of Gaussian process regression to optimally learn compositional functions

no code implementations16 May 2022 Matteo Giordano, Kolyan Ray, Johannes Schmidt-Hieber

We rigorously prove that deep Gaussian process priors can outperform Gaussian process priors if the target function has a compositional structure.

Reconfinement, localization and thermal monopoles in $SU(3)$ trace-deformed Yang-Mills theory

no code implementations24 Dec 2020 Claudio Bonati, Marco Cardinali, Massimo D'Elia, Matteo Giordano, Fabrizio Mazziotti

We show, by means of a finite size scaling analysis, that the reconfinement phase transition is first-order, like the usual $SU(3)$ thermal phase transition.
