I’m excited to be giving the Math and CS Colloquium at UMSL this week. My talk is written and now I’m just trying to get all my reservations together in one spot. Since this is our Fall Break at CMC, I will be staying the weekend in St. Louis, and am looking forward to getting to know the city a little bit.
I will be giving the Statistics Seminar at UCLA on October 18th. The talk is titled: “Perfect simulation of repulsive point processes”.
Abstract Entities in competition for resources, such as towns in a country or trees in a forest, often are further apart from each other than would be predicted if their spatial distribution was independently uniform. Repulsive point processes are used to model such data, but rarely are these distributions given in closed form. Instead, they can be given as either an algorithmic model, or as a unnormalized density with respect to a spatial Poisson point process. In this talk I will show how to generate random samples exactly from an algorithmic setup called the Matérn Type III model, and from an unnormalized density called the Strauss model. Also, I will discuss effective ways to turn these samples into estimates using these models.
The talk that I gave at Greek Stochastics γ has now been posted to the list of talks on my website here. The talk, entitled “The Paired Product Estimator for normalizing constants of Gibbs distribution” details a method for approximation of partition functions that is markedly faster than previously known methods.
The second issue of the Journal of Humanistic Mathematics is now online! As usual, it contains several great pieces about mathematicians doing mathematics, two book reviews, more poetry, and for the first time a short fiction piece. Many thanks to my coeditor Gizem Karaali, who did most of the work getting this issue out this last month. The issue can be accessed here.
Today at 15:00 I am presenting a talk at the Greek Stochastics gamma conference. The topic is an improved version of approximation for the normalizing constant of a Gibbs distribution that requires a number of samples that is linear in the log of the normalizing constant. The title of the talk is “The Paired Product Estimator”.
Tomorrow (Wednesday, 4th May) at 6:30 PM Pacific time, I will be hosting a session with my fellow editor Gizem Karaali on the Journal of Humanistic Mathematics for the weekly series run by Math 2.0.
