Graduate student reading seminar
Tuesdays at 2:30pm, VV B305 for the rest of the semester
I will go over Mike Giles’ 2008 paper “Multi-level Monte Carlo path simulation.” This paper introduced a new Monte Carlo method to approximate expectations of SDEs (driven by Brownian motions) that is significantly more efficient than what was the state of the art. This work opened up a whole new field in the numerical analysis of stochastic processes as the basic idea is quite flexible and has found a variety of applications including SDEs driven by Brownian motions, Levy-driven SDEs, SPDEs, and models from biology
A very quick introduction to Stein's method.
I will give a brief introduction to Stein's method, mostly based on the the first couple of sections of the following survey article:
Ross, N. (2011). Fundamentals of Stein’s method. Probability Surveys, 8, 210-293.
The following webpage has a huge collection of resources if you want to go deeper: https://sites.google.com/site/yvikswan/about-stein-s-method
Note that the Midwest Probability Colloquium (http://www.math.northwestern.edu/mwp/) will have a tutorial program on Stein's method this year.
