(1) Yi Yu (2) Blanca Avuso De Dios (3) Marcus Sarkis ((1) Guangxi University, China. (2) Universita degli Studi Milano-Bicocca, Italy. (3) Worcester Polytechnic Institute, USA.)
(1) "On the ideas of Multigrid, Domain Decomposition, and RAS" (2) "Simple Basic Preconditioning ideas for some Kernel methods" (3) "Two-scale Neural Networks for optimal control of linear convection-dominated equations"
(1) Classical preconditioners for linear systems often fall into two main categories: multigrid method (successive subspace correction, SSC) and domain decomposition method (parallel subspace correction, PSC). In this talk, we focus on domain decomposition methods …

Stochastic PINNs - merging PINNs and stochastic differential equations
The talk presents a new methodology, called stochastic PINNs (StPINNs), for approximating sample paths of stochastic differential equations (SDEs) using artificial neural networks. The method is based on a Doss–Sussman transformation of the initial SDE …

On the power of adaption and randomization
We present bounds between different widths of convex subsets of Banach spaces, including Gelfand and Bernstein widths, and discuss implications for the adaption problem. In particular, we obtain a bound on the maximal gain of …
