Simulation of Rare Events - Methodology UQ

This group will focus on methods for simulating rare events in high-dimensional physical systems, especially PDE models. We will explore the use of importance sampling and large deviation theory in order to identify important mechanisms or configurations of the parameters that lead to rare events. We also will consider the role of asymptotic analysis in constructing effective sampling weights for such computations.

Meeting: Friday March 2nd @ 2pm

Our next meeting is scheduled for this Friday. Due to various reasons, it was decided to postpone last meeting's agenda to the next meeting. So, we will be talking about this paper by Chatterjee and Dey: http://arxiv.org/abs/0906.1034

At our next meeting, It'll be me again, presenting a paper by Chatterjee and Dey, and in a related vein, also discussing a rare event simulation problem for Erdos-Renyi graphs that Shankar, Jim, Jan and I have been working on, if time permits.

The Chatterjee and Dey paper can be found here: http://arxiv.org/abs/0906.1034
