[ibayesclub.beta] reminder: Bayes Club, Friday (11th of June), from 4pm

[Szabo, B.T.]

Dear  Colleagues,

This is a kind reminder that the last International Bayes Club (https://www.math.vu.nl/thebayesclub/) meeting of this academic year will take place tomorrow, on the 11th of June (Friday) from 4 pm (CEST). This time we have only one speaker: Andrew Stuart (Caltech). Please find below the title and abstract of his talk. After the talks we will open up our  virtual meeting place at gather.town so if you want to hang out and perhaps have a beer virtually with your colleagues then you are invited to join. Since this is the last seminar of the semester it would be great if many of you could join even just for a short while.

The seminar will be on zoom:


Topic: International Bayes club
Time: Jun 11, 2021 04:00 PM Amsterdam, Berlin, Rome, Stockholm, Vienna

Title: Solving PDEs With Gaussian Processes

Coauthors: Yifan Chen, Bamdad Hosseini and Houman Owhadi

Abstract:
We describe an approach to solving PDEs in which the solution
is found by minimizing a squared RKHS norm subject to a penalty,
or constraint, defined via the PDE. This links to the subject of
Gaussian processes subject to pointwise nonlinear constraints.
We introduce a framework for the methodology, establish convergence
of the resulting numerical method, and describe numerical results.
Forward problems for a nonlinear elliptic PDE, Burgers' equation
and a regularized Eikonal equation are presented; and the method
is extended to inverse problems and applied to the problem of
permeability identification in the Darcy model of flow in a porous medium.

Best wishes,
Botond
(on behalf of the organisers)
