5th SFB 1294 Kálmán Lecture with Nicolas Chopin

We are delighted that Nicolas Chopin from ENSAE, Institut Polytechnique de Paris, France, will be guest for the 5th SFB 1294 Kálmán Lecture.

Title: Nested cubing integration: how to get a O(N{-10}) error when you compute your favourite integral

Abstract

This talk will explain why computing integrals remains such an important task in applied mathematics, in particular in Statistics and machine learning. I will present several known methods to get unbiased estimates of an integral, and an old result giving the best achievable error rate given the number of evaluations and the regularity of the function. I will then present a new method, developed with Mathieu Gerber, which attains this rate. The underlying ideas of this method are surprisingly simple, and rely on concepts covered in undergraduate courses.
