Tao Zhao – Best Student Paper Award

Mr. Tao Zhao, a PhD Student in the Department of Electrical and Computer Engineering at Texas A&M University, and his advisor Dr. I-Hong Hou are proud to announce that Tao Zhao has won the Best Student Paper award of the 15th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks (WiOpt 2017) in Paris, France. Zhao co-wrote the paper “A Non-Monetary Mechanism for Optimal Rate Control Through Efficient Delay Allocation” with Dr. I-Hong Hou and Dr. Korok Ray.

Their paper proposes a practical non-monetary mechanism that induces the efficient solution to the optimal rate control problem, where each client optimizes its request arrival rate to maximize its own net utility individually, and at the Nash Equilibrium the total net utility of the system is also maximized. Existing mechanisms typically rely on monetary exchange which requires additional infrastructure that is not always available. Instead, the proposed protocol is based on efficient delay allocation, where the server controls the delay experienced by each client through an intelligent scheduling policy. Specifically, they present an efficient delay allocation rule for the server to determine the target delay of each client. Then they propose a simple scheduling policy to achieve such delay allocation. Furthermore, they design a distributed rate control protocol for the system to converge to the Nash Equilibrium. The optimality of their mechanism is validated via extensive simulations on two representative systems against a baseline mechanism with FIFO scheduling and centralized rate control.

Congratulations Tao Zhao!

Satchidanadnan wins best student paper award at COMSNETS 2017

Bharadwaj Satchidanadnan, a graduate student in the Department of Electrical and Computer Engineering at Texas A&M University, won the best student paper award in the 9th International Conference on Communication Systems and Networks (COMSNETS 2017) in Bangalore, India.
Satchidanadnan co-wrote the paper “On Minimal Tests of Sensor Veracity for Dynamic Watermarking-Based Defense of Cyber-Physical Systems,” with his Ph.D. adviser, Dr. P.R. Kumar from the Computer Engineering and Systems Group.

Their paper addresses the problem of secure control of networked cyber-physical systems. More specifically, they consider the problem of controlling a physical plant with multiple inputs and multiple outputs, where the sensors measuring some of the outputs may be malicious. The malicious sensors can collude and report false measurements, fabricated possibly strategically, in order to achieve any objective that they may have, such as destabilizing the closed-loop system or increasing its running cost. In his paper, Satchidanadnan proposes a general technique termed Dynamic Watermarking, which allows the controller to detect such malicious sensors in the system and prevent them from causing performance degradation.

Satchidanandan earned his master’s degree from the Indian Institute of Technology, Madras, India, where he worked on wireless communications. Between May 2015 and August 2015, he interned at Intel Labs in Santa Clara, California, where he worked on interference cancellation algorithms for next generation wireless networks. His research interests include cyberphysical systems, power systems, security, database privacy, communications, control and signal processing.

Duffield receives NSF grant to explore network traffic classification

Dr. Nick Duffield, a professor in the Department of Electrical and Computer Engineering at Texas A&M University, was awarded a grant from the National Science Foundation (NSF) that will allow him to research network traffic classification.

Duffield, in collaboration with Dr. Minlan Yu from Yale University, received the grant, which is titled “Distributed Approximate Packet Classification.” It is funded from 2016 to 2019 with a budget of $350,000.

Network traffic classification — assigning incoming packets to classes for processing based on pattern-matching rules — is critical for many network management tasks, including performance monitoring and fault diagnosis. However, as the number of classification tasks grows, the resources required to store and apply the rules, switch memory in particular, can become scarce. Duffield’s project takes an end-to-end view of traffic classification, observing that in addition to the memory usage at switches, other cheaper resources are involved in packet processing, specifically bandwidth to transfer selected packets to the receivers and downstream receivers that run applications. Trading off resources and even classification accuracy amongst these resources can lead to a better overall performance once the needs of downstream applications are factored in.

“The big research challenge now is how to realize these benefits in large and complex communications networks, such as in data centers, which can encompass millions of servers connected by hundreds of thousands of switches,” Duffield said.

Duffield, who also has a courtesy appointment in the Department of Computer Science and Engineering and is director of the Texas A&M Engineering Big Data Initiative, received his bachelor’s degree in natural sciences in 1982 and a master’s in mathematics in 1983 from the University of Cambridge. He received his Ph.D. in mathematical physics from the University of London in 1987. His research focuses on data and network science, particularly applications of probability, statistics, algorithms and machine learning to the acquisition, management and analysis of large datasets in communications networks and beyond.

Before joining the department, Duffield worked at AT&T Labs-Research, Florham Park, New Jersey, where he held the position of distinguished member of technical staff and was an AT&T Fellow. He previously held post-doctoral and faculty positions in Dublin, Ireland, and Heidelberg, Germany.

Duffield, the author of over 150 refereed journal and conference papers and inventor of 50 U.S patents, is co-inventor of the smart sampling technologies that lie at the heart of AT&T’s scalable Traffic Analysis Service. He is specialty editor-in-chief for Big Data of the journal Frontiers in ICT and he was charter chair of the IETF working group on packet sampling. Duffield is an IEEE Fellow, an IET Fellow and serves on the board of directors of ACM SIGMETRICS. He is an associate member of the Oxford-Man Institute of Quantitative Finance. He is a Texas A&M principal investigator on the DARPA funded consortium DEDUCE: Distributed Enclave Defense Using Configurable Edges, and has received faculty research awards from Google and Intel.

Gratz receives Association of Former Students Distinguished Achievement Award in Teaching

Dr. Paul V. Gratz, associate professor in the Department of Electrical and Computer Engineering at Texas A&M University, was awarded the 2016 Association of Former Students (AFS) Distinguished Achievement Award in Teaching — College Level. He is one of four faculty members in the college of engineering selected to receive the award.

Since 1982, the AFS teaching award has been presented to faculty members who are renowned for their expertise and exemplary dedication to the education of their students.

Dr. Miroslav Begovic, electrical and computer engineering department head, said Gratz deserves the award because he has been an early adopter of blended learning within the department and college, having restructured ECEN 350 as a blended learning class.

The restructured class features live, recorded lectures published online and online quizzes replacing traditional homework, among other enhancements. Those efforts have yielded two benefits — a two to three week increase in material covered during a semester as well as improvements in student retention from a traditionally high drop-rate class.

Gratz has also been a leader in the department’s efforts to develop a distance learning masters program. His ECEN 676 class during spring 2016 served as the pilot class for the distance learning masters program. Based on his experiences he is developing a set of distance learning training sessions for faculty.

Gratz is a member of the computer engineering and systems group. He received his Ph.D. in electrical and computer engineering from the University of Texas at Austin in 2008. His research interests include energy-efficiency, reliability and performance in processor microarchitectures, memory systems and on-chip interconnection networks.

He has received a Teaching Excellence Award from The Texas A&M University System and a Best Paper Award from the ASPLOS’09 conference.

The AFS teaching award will be formally presented to all recipients in spring 2017 at the annual college awards banquet.

Researchers in electrical and computer engineering receive award for brain-inspired computing

Two graduate students and their adviser in the Department of Electrical and Computer Engineering at Texas A&M University received the Honorary Mention Best Paper Award from the 2016 IEEE International Symposium on Circuits and Systems (ISCAS).

Qian Wang, Youjie Li and their thesis adviser, Dr. Peng Li, received the award for their paper titled, “Liquid state machine based pattern recognition on FPGA with firing-activity dependent power gating and approximate computing,” at ISCAS, which was held in Montreal, Canada. This award was conferred by the Neural Systems and Applications Technical Committee of IEEE Circuits and Systems (CAS) Society.

For a very long time, the human brain has been a great inspiration for building efficient intelligent systems. Nevertheless, mimicking the information processing capabilities of the brain in VLSI-based computing systems is a completely nontrivial task and entails the development of efficient processor architectures and hardware-friendly learning mechanisms. The researchers’ paper demonstrates how the liquid state machine (LSM), a biologically plausible recurrent spiking neural network model, can be used to enable brain-inspired neural processors. An LSM processor architecture with integrated on-chip learning capability has been demonstrated on the reconfigurable FPGA platform for pattern and speech recognition applications. This work also investigates novel firing activity-based low power and approximate computing techniques to boost system energy efficiency.

Wang and Li are part of Dr. Li’s research group, and have recently passed their Ph.D. and M.S. thesis defenses, respectively. Dr. Li is a professor in the department, a faculty member of the Texas A&M Institute for Neuroscience and Texas A&M Health Science Center, and an IEEE Fellow. In addition to this award, Dr. Li has received five other best paper awards from premier IEEE/ACM conferences.

ISCAS is the world’s premier networking forum of leading researchers in the highly active fields of theory, design and implementation of circuits and systems.

Second Big Data workshop fosters connections across disciplines at Texas A&M University

The second annual Big Data workshop was held recently at Texas A&M University to foster connections across disciplines that intersect this area and help people to continue to identify opportunities for collaboration. The workshop was comprised of 27 short talks from speakers from across the university, organized in thematic sessions with time for discussion. The sessions encompassed Big Data in Sensing and Social Applications; Environment, Resources and Power; Materials; Cybersecurity; and Bioinformatics, Medicine & Health Sciences. Participants also discussed broader issues for big data research in the university, including infrastructure support, computational resources and availability of data for collaboration. There were over 90 registered attendees.

Many researchers across Texas A&M have current or emerging research interests in big data methods, systems or applications, and there are currently opportunities at the federal level for major funding of cross-disciplinary projects in data science.

Building on the first workshop held last year, Dr. Nick Duffield, professor in the Department of Electrical and Computer Engineering and director of the Texas A&M Engineering Big Data Initiative, and Dr. Dilma Da Silva, head of the Department of Computer Science and Engineering, organized the workshop to continue to build community amongst big data researchers at Texas A&M.

Since the first workshop, interdisciplinary teams from Texas A&M have submitted proposals for funding opportunities including the NSF BIGDATA and NSF Big Data Spokes programs. In order to help researchers better position themselves for these and other opportunities, the Texas A&M Engineering Experiment Station (TEES), in partnership with the Texas A&M Division of Research, Texas A&M AgriLife Research, Texas A&M Health Science Center (TAMHSC) and the Texas A&M Transportation Institute (TTI), has awarded nearly $350,000 in seed grant funding to seven interdisciplinary research teams for big data.

“Texas A&M is positioned to lead in applications of big data in its disciplinary areas of strength, not only in research, but by leveraging its network of cross-sector partnerships to realize the benefits of big data applications more widely,” said Duffield. Texas A&M will host a conference on “Advances in Big Data Modeling, Computation and Analytics,” on Sept.22-24, which will feature leading researchers and practitioners in the field.
