Title : Some Recent Advances in Compressed Sensing
Date  : Thursday, July 25, 2013
Time  : 11 AM - 12 Noon
Venue : CSA Lecture Hall (CSA 117)


Abstract:
-------
Compressed sensing refers to the ability to reconstruct high-dimensional
but sparse vectors on the basis of just a small number of measurements.
Current proofs in the area make use of nothing more than undergraduate
linear algebra.  In this talk I will survey some of the most important
theorems in the area, leading up to "near ideal behaviour of the LASSO
algorithm."  Then I will present a recent result, showing that the
LASSO is just one amongst a infinite class of algorithms, all of which
permit exact reconstruction of sparse signals, and all of which exhibit
near ideal behaviour.  The talk will be interactive and will not
presuppose any prior familiarity with the area.

Biography:
---------
Mathukumalli Vidyasagar was born in Guntur, India on September 29, 1947.
He received the B.S., M.S. and Ph.D. degrees in electrical engineering
from the University of Wisconsin in Madison, in 1965, 1967 and 1969
respectively. Between 1969 and 1989, he was a Professor of Electrical
Engineering at Marquette University, Milwaukee (1969-70), Concordia
University, Montreal (1970-80), and the University of Waterloo, Waterloo,
Canada (1980-89). In 1989 he returned to India as the Director of the
newly created Centre for Artificial Intelligence and Robotics (CAIR) in
Bangalore, under the Ministry of Defence, Government of India. Between
1989 and 2000, he built up CAIR into a leading research laboratory with
about 40 scientists and a total of about 85 persons, working in areas such
as flight control, robotics, neural networks, and image processing. In
2000 he moved to the Indian private sector as an Executive Vice President
of India's largest software company, Tata Consultancy Services. In the
city of Hyderabad, he created the Advanced Technology Center, an
industrial R&D laboratory of around 80 engineers, working in areas such as
computational biology, quantitative finance, e-security, identity
management, and open source software to support Indian languages.

In 2009 he retired from TCS and joined the Erik Jonsson School of
Engineering & Computer Science at the University of Texas at Dallas, as a
Cecil & Ida Green Chair in Systems Biology Science. In March 2010 he was
named as the Founding Head of the newly created Bioengineering Department.
His current research interests are in the application of stochastic
processes and stochastic modeling to problems in computational biology,
and control systems.

Vidyasagar has received a number of awards in recognition of his research
contributions, including Fellowship in The Royal Society, the world's
oldest scientific academy in continuous existence, the IEEE Control
Systems (Field) Award, the Rufus Oldenburger Medal of ASME, and others. He
is the author of ten books and nearly 140 papers in peer-reviewed
journals. For more details:
