Hi all!
We will have a researcher from MIT, Bart Van Parys, giving a talk on Friday Jan 26th at 1:30PM in room AA1360.
Note the later time, 1:30!
This
is a seminar is organized in collaboration with the Canada Research
Chair in Decision Making under Uncertainty at GERAD! So this is ideal
for all the optimization fans out there!
Based on my experience, this will be a great talk and coming to it should be an easy decision!

TITLE Modern Optimization for Sparse Learning and Robust Analytics
ABSTRACT We discuss the tremendous potential of integer optimization
methods for learning predictive models from high-dimensional data via
exact sparse regression. We show that novel integer formulations can
solve exact sparse regression problems of sizes counting p=100,000s
covariates for n=10,000s of samples. That is, two orders of magnitude
more than current state of the art methods. We also indicate that robust
optimization methods can help practitioners make data-driven decisions
which are safeguarded against over-calibration to one particular data
set. We claim that robust optimization methods have an enormous untapped
potential when making subsequent decisions based on data.
