Hi all, 

Following are the details for this week's AIIS 
(http://l2r.cs.uiuc.edu/~cogcomp/aiis/) 
talk. 

When: Friday, Oct 22, 2-3 pm. 

Where: 3405 SC. 

Speaker: Prof. Angelia Nedich 
(https://netfiles.uiuc.edu/angelia/www/nedich.html) 

Title: Random Algorithms for Convex Minimization Problems 

Abstract: New applications in communication and control networks, as well as 
large 
data sets processing have given rise to optimization problems with large 
and/or 
dynamically changing constraints. In this talk, we will consider such an 
instance 
where the constraint sets are unknown but they can be observed and learned 
over 
time. We will discuss some algorithmic approaches for solving such problems 
with 
convex structure. The algorithms rely on random projections on the constraint 
sets, 
as the sets are learned. We investigate convergence properties of the 
algorithms and 
also provide some error bounds on the algorithms’ performance both in time 
and 
asymptotic. 

Bio: Angelia Nedich received her B.S. degree from the University of 
Montenegro 
(1987) and M.S. degree from the University of Belgrade (1990), both in 
Mathematics. 
She received her Ph.D. degrees from Moscow State University (1994) in 
Mathematics 
and Mathematical Physics, and from Massachusetts Institute of Technology in 
Electrical Engineering and Computer Science (2002). She has been at the BAE 
Systems Advanced Information Technology from 2002-2006. In Fall 2006, as 
Assistant Professor, she has joined the Department of industrial and 
Enterprise 
Systems Engineering at the University of Illinois at Urbana-Champaign, USA.  
She is 
the recipient of the NSF CAREER Award 2008 in Operations Research for her 
work in 
distributed multi-agent optimization. 

Her general interest is in optimization including fundamental theory, models, 
algorithms, and applications. Her current research interest is focused on 
large-scale 
optimization, ergodicity and consensus, distributed in-network optimization 
and their 
applications 

Hoping to see you all there. 
Best, 
Rajhans
