[Turkmath:7492] PhD Position at the University of Twente

[Fatma Senguler Ciftci]

   PhD Position at the University of Twente
   ==============================

A full-time PhD position is available within the project

   Smoothed Analysis of Belief Propagation

in the group Discrete Mathematics and Mathematical Programming (DMMP) at
the Department of Applied Mathematics. The project is funded by
Netherlands Organization for Scientific Research (NWO) and is embedded
in the University of Twente's Centre for Telematics and Information
Technology (CTIT), the largest academic ICT research institute in the
Netherlands.

REQUIREMENTS

The successful candidate should have a Master's degree in Mathematics,
Computer Science, Econometrics, or a related field. A solid background
in Discrete Optimization, Theoretical Computer Science, or the Analysis
of Algorithms is highly appreciated but not a must as the candidate will
be given the opportunity to follow courses in the LNMB PhD program
during her/his first year (see www.lnmb.nl).

WHAT WE OFFER

We offer a 4-year research position in a dynamic and international
environment. The DMMP group consists currently consists of 10 faculty
members and 13 PhD students and is headed by Prof. Marc Uetz. Please see
www.utwente.nl/ewi/dmmp/ for more details. The University of Twente
provides excellent campus facilities, and actively supports professional
and personal development.

PROJECT DESCRIPTION

Belief propagation is a heuristic approach for solving large-scale
statistical inference problems. It is an easy-to-implement heuristic has
become very popular in a wide range of applications.
Its success in practice, however, is at sharp contrast to the lack of
theoretical understanding of its performance. To provide a more
realistic analysis of algorithms, the concept of smoothed analysis has
been developed. In smoothed analysis, performance is not measured in
terms of worst-case instances. Instead, an adversary specifies an
instance, and then the expected performance is measured when this
instance is slightly randomly perturbed. Smoothed analysis takes into
account that practical data is often noisy, e.g., due to measurement errors.
The aim of this project is smoothed analysis of belief propagation. The
goal is to get a deeper understanding of its performance and to bridge
the gap between theoretical and practical performance of belief propagation.
