July 30, 2010 DL talk: Understanding and Managing Interference in Wireless Networks

Speaker: Prof. Venugopal V. Veeravalli

Electrical & Computer Engineering Dept., University of Illinios at Urbana-Champaign, USA

 

·        Time: Friday, July 30, 2010, 3:30pm to 4:30pm

Abstract:

The understanding of point-to-point wireless communications channels with fading and receiver thermal noise is mature. Recent advances, particularly in the area of multiantenna communications, have led to significant increases in the capacity and reliability of point-to-point links. However, modern wireless networks are limited by interference from other links. While the information theory for interference networks is still in its infancy, several techniques are being explored in the research community for managing interference, while maintaining high spectral spatial reuse efficiencies in these networks. These techniques include spatial user separation, interference cancellation, user cooperation and relaying, dynamic spectrum access, and interference alignment. The first half of this talk will be an overview of these techniques. In the second half of this talk, we will discuss some of our recent results towards an understanding of the information-theoretic capacity of interference networks.  We first discuss a partial solution to the capacity of the two-user interference channel in the weak interference regime, a problem that has been open for more than thirty years. We also discuss new techniques for exploiting partial transmitter cooperation in interference channels in optimal ways.

Abstract:

With recent advances in multimedia, communications and networking technologies, peer-to-peer (P2P) live streaming becomes increasingly popular, and we have seen many successful deployments, for example, PPLive, CoolStreaming, Sopcast, etc. To provide reliable and satisfactory level of service, it is of crucial importance to stimulate user cooperation, to understand how users interact with each other, and to analyze the impact of human factors on P2P live streaming systems. Such an understanding provides fundamental guidelines to better design of P2P live streaming systems, and to offer more secure and personalized services. Human and social dynamics has recently been identified by US National Science Foundation as one of its five priority areas, which also shows the importance of this emerging interdisciplinary research area. This talk introduces our recent works on cooperation stimulation for P2P live streaming systems. First, the mesh-pull peer-to-peer live streaming systems will be introduced. Then, a game-theoretic framework will be proposed to model and analyze user dynamics in P2P live streaming and to stimulate user cooperation. Finally, different defensive mechanisms will be explored to resist pollution attacks and stimulate user cooperation even under attacks.

June 3, 2010 DL talk: Structural Results in Networked Sensor Management

Speaker: Prof. Vikram Krishnamurthy

Electrical & Computer Engineering Dept., University of British Columbia, Canada

 

·        Time: Thursday, June 3, 2010, 3:30pm to 4:30pm

·        Location: Room KAIS 2020, Fred Kaiser Building (2332 Main Mall), University of British Columbia

Abstract:

This seminar deals with sensor activation and social learning in sensor networks using game theoretic and stochastic control methods.The talk comprises of three parts. In the first part, we describe how social learning leads to rational herding and how optimized social learning has a threshold structure on the simplex of Bayesian posterior distributions. In the second part of the talk, we illustrate how the theory of global games gives a powerful method for designing decentralized data-aware sensor activation algorithms in dense sensor networks. We show that the Nash equilibrium of the sensor network has a simple threshold structure and exhibits a remarkable phase transition as more data is collected. In the third part of the talk we describe how decentralized adaptive filtering algorithms with regret matching can be deployed in sensor networks to guide network behavior to a correlated equilibrium. A major theme of the talk will be the focus on structural properties and convergence analysis that result in numerically efficient algorithms rather than brute force computational methods.

Abstract:

Particle filtering is a Monte Carlo – based methodology for sequential signal processing. It is designed for estimation of hidden processes that are dynamic and that can exhibit most severe nonlinearities. Also, it can be applied with equal ease to problems that involve any type of probability distributions. Therefore, it is not surprising that particle filtering has gained immense popularity. In this talk, first, the basics of particle filtering will be provided with description of its essential steps. Then some important topics of the theory will be addressed including Rao-Blackwellization, smoothing, and estimation of constant parameters.  Finally, a presentation of most recent advances in the theory will be given. The talk will contain signal processing examples which will aid in gaining valuable insights about the methodology.

     Oct. 5, 2009 talk: Developments in Biometric Templates Protection

Speaker:  Dr. Ton Kalker

Multimedia Communications & Networking Lab, HP Labs, Palo Alto, CA, USA

 

·        Time: Monday, Oct. 5, 2009, 3:00pm to 4:00pm

·        Location: Room KAIS 2020, Fred Kaiser Building (2332 Main Mall), University of British Columbia

Abstract:

An unfortunate side effect of the growth of the Internet and its associated services is an increasing need to securely store and manage a multitude of user identities and passwords. Very often the numbers that need to be managed are too large to be practical, and people resort to re-using passwords and/or using simple (and guessable) schemes for password generation. Biometrics is often proposed as a way out of this dilemma: biometric data are unique to a person, they are hard to replicate, and they don't need to be remembered. However, biometric data for authentication suffer from a number of potential pitfalls that need to be resolved before they can replace classical password schemes. One example would be the lack of renewability of a biometric template: once a biometric template has been compromised, there is no obvious way to renew authentication data. In this talk, we will give an overview of issues around biometric template detection, addressing both threats and potential solutions. In particular we will discuss some recent results on the rate of biometric authentication schemes as a function of biometric information leakage.

Abstract:

Computers, communication, and sensing technologies are converging to change the way we live, interact, and conduct business. Wireless sensor networks reflect such convergence. These networks are based on collaborative efforts of a large number of sensor nodes. They should be low-cost, low-power, and multifunction. These nodes have the capabilities of sensing, data processing, and communicating. Sensor networks have a wide range of applications, from monitoring sensors in industrial facilities to control and management of energy applications to military and security fields. Because of the special features of these networks, new network technologies are needed for cost effective, low power, and reliable communication. These network protocols and architectures should take into consideration the special features of sensor networks such as: the large number of nodes, their failure rate, limited power, high density, etc. In this talk the impact of wireless sensor networks will be addressed, several of the design and communication issues will be discussed, and a case study of a current project of using such networks in drilling and management off-shore oil and natural gas in the gulf region will be given.

·        Location: Room KAIS 2020, Fred Kaiser Building (2332 Main Mall), University of British Columbia

Abstract:

In a wireless network, transmission activities can be easily monitored using simple devices. Given the record of transmissions from a set of nodes, one may be able to ascertain whether these nodes are engaged in some networking operations.  While the content of a wireless transmissions can be protected by cryptographical techniques, the acts of transmission may reveal critical information about network operations such as routing and multicasting.

In this talk, we consider two related problems. The first is the problem of flow detection: given observations from a set of traffic sensors, to what extent can the presence of an information flow be detected?  We present results on the fundamental limit of detectability. The second probem is anonymous networking: to what extent can we hide an information flow. Here we use information theoretic measures to characterize the tradeoff between anonymity vs. network throughput.

May 8, 2008 talk: From Image Analysis to Content Extraction: Are We There Yet?

Speaker: Prof. Tsuhan Chen

IEEE Signal Processing Society Distinguished Lecturer

Professor

ECE Dept., Carnegie Mellon University, Pittsburgh, USA

Time: Thursday, May. 8th, 2008, 2:00pm to 3:00pm

Location: Room KAIS 2020, Fred Kaiser Building (2332 Main Mall), University of British Columbia

Abstract

Traditionally, image processing is considered low-level processing. In the past decade, image processing has grown to become an area where a variety of tools are created to solve high-level problems that conventionally would be studied exclusively by computer vision or machine learning researchers.  For example, multi-resolution analysis inspired popular image features like SIFT (scale-invariant feature transform), and statistical analysis gave birth to graphical models including HMM (hidden Markov models) and topic models.  In this talk, we will use one application to illustrate this trend, object discovery, i.e., extracting the "object of interest" from a set of images in a completely unsupervised manner.  Based on image features like SIFT, and the topic models, we will outline our approach to object discovery and apply it to both still images and motion videos. We will propose a novel spatial-temporal framework that applies statistical models to both appearance modeling and motion modeling. The spatial and temporal models are integrated so that motion ambiguities can be resolved by appearance, and appearance ambiguities can be resolved by motion.  In addition, we will show how hierarchical relationships among objects can be extracted completely from images without any manual labeling.

October 15, 2007 talk: On the Root of Digital Signal Processing

Speaker: Dr. Andreas Antoniou

IEEE Circuits and Systems Society Distinguished Lecturer

Professor Emeritus

Department of Electrical and Computer Engineering

University of Victoria, BC, Canada 

Time: Part II: Monday, October 15, 2007, 2:00pm to 3:00pm

Location: Room KAIS 2020, Fred Kaiser Building (2332 Main Mall), University of British Columbia

Abstract

The roots of what we refer to today as digital signal processing are actually the roots of modern mathematics, and to trace the evolution of DSP we need to go back to the 1600s even to the mathematical world of classical Greece. These two lectures, one at SFU and the other at UBC, will attempt in a not-so-rigorous exposition to outline the major historical landmarks that led to DSP. This subject of study, which has become a multifaceted discipline in recent years, comprises three fundamental processes, namely, discretization (or sampling), processing, and interpolation. Discretization concerns the conversion of a function of one or more continuous independent variables into numbers; processing entails converting or transforming the numbers obtained through discretization into some other form that is in some way or another more desirable; interpolation involves converting the set of processed numbers into a continuous function. Therefore, in our search for the roots of DSP, we must search for the origins of discretization, processing of numerical data, and interpolation.

UBC Lecture: : On the Roots of Digital Signal Processing - 1770 to 1970

Oct. 15, 2007, 2:00pm to 3:00pm, Room KAIS 2020, Fred Kaiser Building, UBC

The second lecture will deal with certain landmark discoveries over the period 1770 to 1970. It will demonstrate that the mathematical tools for spectral analysis were introduced by a group of French mathematicians who studied or taught at Ecole Polytechnic in Paris during or soon after the French Revolution over a period of no more than 50 years or so. Lagrange and Laplace were teachers of Fourier and Poisson, Fourier was a teacher of Derishlet, and Poisson took the Chair of Fourier when the latter was appointed a Prefect in Grenoble by Napoleon. The processing of numerical data by machines was explored by many, including Pascal and Leibniz, but the most ambitious attempt was by Babbage who is often regarded to be the father of computing. However, the presentation will show that contrary to popular belief, what Babbage attempted to do during his entire professional life was to build a mechanical discrete system that would compute the entries of numerical tables and also print the tables in a single consolidated operation. The lecture will also deal with the origins of the sampling theorem which is attributed to Nyquist and/or Shannon. Actually, this famous theorem was discovered independently by several engineers or scientist around the 1930s and 1940s but the underlying principles were known to mathematicians long before that time and are closely related to an interpolation method due to the great Lagrange.

Feb. 28, 2008 talk: Joint Coding and Embedding Framework for Multimedia Fingerprinting

Speaker: Dr. Shan He

Researcher, Thomson Corporate Research, Princeton, USA

Time: Thursday, Feb. 28, 2008, 4:30pm to 5:30pm

Location: Room KAIS 2020, Fred Kaiser Building (2332 Main Mall), University of British Columbia

Abstract

Digital fingerprinting protects multimedia content from illegal redistribution by uniquely marking every copy of the content distributed to each user. One powerful attack against fingerprinting is called collusion attack, where several different fingerprinted copies of the same content are combined together to attenuate or even remove the fingerprints. A major category of collusion-resistant fingerprinting employs an explicit step of coding. Most existing works on coded fingerprinting mainly focus on the code-level issues and treat the embedding issues through abstract assumptions without examining the overall performance. Moreover, in practical applications such as video-on-demand distribution, the potential users can be as many as 10 to 100 million. This large user size demands not only strong collusion resistance but also high efficiency in the fingerprint construction and detection. In this work, we jointly consider the coding and embedding issues and propose a fingerprinting framework which provides a promising balance between collusion resistance, efficient construction and detection. Further, we explore how to employ such a framework and develop practical algorithms to fingerprint video in challenging settings as to accommodate more than ten million users and resisting hundreds of users' collusion. Results show a high potential of joint coding and embedding to meet the needs of real-world large-scale fingerprinting applications.
