CCI Winter Speaker Series: Analysis and Algorithms for the Phase Retrieval Problem

Order: Reorder
Duration: 53:51
Updated: 28 Jan 2014

Joint Math-CS Lecture by Radu Balan (Department of Mathematics and Center for Scientific Computation and Mathematicl Modeling, University of Maryland) // Title: Analysis and Algorithms for the Phase Retrieval Problem // Abstract: The phase retrieval problem presents itself in many applications is physics and engineering. Recent papers on this topic present examples ranging from X-Ray crystallography to audio and image signal processing, classification with deep networks, quantum information theory, and fiber optics data transmission. The problem is to reconstruct a vector in a Hilbert space, up to a global phase factor, from magnitudes of inner products with vectors of a given frame. Two fundamental problems are: (i) analysis of frame sets when inversion is possible; and (ii) efficient algorithms to perform inversion, when possible. In this talk I will describe recent results regarding these problems including descriptions of the Cramer-Rao lower bound as well as other robustness measures for any inversion algorithm. // Bio: Radu Balan received the B.S. degree in E.E. from Polytechnic Institute of Bucharest (1992), B.S. in Physics from University of Bucharest (1994), both in Romania, and the Ph.D. degree in Applied Mathematics from Princeton University in 1998. During the year 1998-1999 he was a postdoctoral associate at IMA (Minneapolis, MN) jointly with IBM T.J. Watson (Hawthorn, NY). From 1999 to 2007 he was a (Senior) Research Scientist with Siemens Corporate Research, in Princeton, NJ, working on the Blind Source Separation problem and other statistical signal processing algorithms. In 2007 he joined the University of Maryland in the Department of Mathematics and the Center for Scientific Computation and Mathematical Modeling (CSCAMM) where he currently is a Professor in Applied Mathematics. His research interests include applied harmonic analysis, statistical data processing, and machine learning.

Duration: 2:31
Updated: 13 Nov 2013

The aim of this symposium is to provide a forum for researchers and technologists to present new ideas and contributions in the form of technical papers, panel discussions as well as real-world evaluation of many ideas in wireless communications, networking and signal processing employed to support the needs of the Information Society. This eleventh symposium will bring together various wireless communication systems developers to discuss the current status, technical challenges, standards, fundamental issues, and future services and applications. ISWCS'14 seeks to address and capture highly-innovative and state-of-the-art research from academia, the wireless industry as well as standardization advances. The scope of the conference includes a wide range of technical challenges encompassing wireless communications, information theory, quality of service support, networking, signal processing, cross-layer design for improved performance, and future wireless broadband systems. - See more at: http://www.cttc.es/2013/10/24/cttc-coorganizes-the-iswcs2014/#sthash.jmRIr40a.dpuf

Updated: 10 Sep 2013

just in case you dont know what this means here is a definition he Nyquist--Shannon sampling theorem, after Harry Nyquist and Claude Shannon,[1] in the literature more commonly referred to as the Nyquist sampling theorem or simply as the sampling theorem, is a fundamental result in the field of information theory, in particular telecommunications and signal processing. Sampling is the process of converting a signal (for example, a function of continuous time or space) into a numeric sequence (a function of discrete time or space). Shannon's version of the theorem states:[2] If a function x(t) contains no frequencies higher than B hertz, it is completely determined by giving its ordinates at a series of points spaced 1/(2B) seconds apart. In other words, a bandlimited function can be perfectly reconstructed from a countable sequence of samples if the bandlimit, B, is no greater than half the sampling rate (samples per second). The theorem also leads to a formula for reconstruction of the original function from its samples. When the bandlimit is too high (or there is no bandlimit), the reconstruction exhibits imperfections known as aliasing. The Poisson summation formula provides a graphic understanding of aliasing and an alternative derivation of the theorem, using the perspective of the function's Fourier transform.

CMSV-DLS - 140305 with Vincent Poor

Order: Reorder
Duration: 63:08
Updated: 07 Mar 2014

Abstract: Smart grid involves the imposition of an advanced cyber layer atop the physical layer of the electricity grid in order to improve the efficiency and lower the cost of power use and distribution, and to allow for the effective integration of variable energy sources and storage modes into the grid. This cyber-physical setting motivates the application of many techniques from the information and systems sciences to problems arising in the electricity grid, and considerable research effort has been devoted to such application in recent years. This talk will describe recent work on three aspects of this problem: applications of game theory to the modeling of the interactions of nodes on the grid; characterization of the fundamental tradeoff between privacy and utility of information sources arising in the grid; and distributed inferential algorithms that are suitable for the topological constraints imposed by the structure of the grid. Speaker Bio: H. Vincent Poor is the Michael Henry Strater University Professor of Electrical Engineering at Princeton, where he is also Dean of the School of Engineering and Applied Science. His research interests are in the areas of information theory, statistical signal processing and stochastic analysis, and their applications in smart grid, wireless networks and related fields. His publications in these areas include the recent book Mechanisms and Games for Dynamic Spectrum Allocation, published by Cambridge University Press in 2014. Dr. Poor is a Fellow of the IEEE and a member of the National Academy of Engineering and the National Academy of Sciences.
