IAM-PIMS-MITACS Distinguished Colloquium -Approximating Functions in High Dimensions

  • Date: 04/19/2010
Lecturer(s):
Albert Cohen (Université Pierre et Marie Curie)
Location: 

University of British Columbia

Description: 

This talk will discuss mathematical problems which are challenged by the fact they involve functions of a very large number of variables. Such problems arise naturally in learning theory, partial differential equations or numerical models depending on parametric or stochastic variables. They typically result in numerical difficulties due to the so-called “curse of dimensionality”. We shall explain how these difficulties may be handled in various contexts, based on two important concepts: (i) variable reduction and (ii) sparse approximation.

Schedule: 

3:00-4:00 pm,

Rm 301, Leonard S. Klinck Building (6356 Agricultural Road, UBC).

 

Refreshments will be served 15 minutes prior to the talk in room 306 (IAM Lounge).
