Speaker: Ramtin Pedarsani, University of California, Santa Barbara
Talk Title: Robust Scheduling for Flexible Stochastic Networks
Abstract: Modern large-scale stochastic systems face much demand and processing variability, and a key challenge is the design of efficient control and scheduling policies that are robust to these uncertainties. In this talk, I will present several robust scheduling policies for stochastic models with applications to emerging sectors such as data centers and intelligent transportation systems. In the first part, I present a robust scheduling policy with performance guarantee, for a novel stochastic model of job scheduling in data centers, where jobs are represented as directed acyclic graphs (DAG). I will then visit the long-standing open problem on the stability of of the longest-queue-first scheduling policy for multiclass open queueing networks, and resolve this problem for an important special case. In the second part of the talk, I focus on transportation networks. I develop the first exact analysis of fixed-time control for urban networks, and briefly mention a few opportunities and challenges in exploiting autonomous vehicles for enhancing network's performance.
Biography: Ramtin Pedarsani is an assistant professor in the ECE department at UCSB. He obtained his Ph.D. in Electrical Engineering and Computer Sciences from UC Berkeley in 2015. He received his M.Sc. degree at EPFL in 2011 and his B.Sc. degree at the University of Tehran in 2009. His research interests include stochastic networks, information and coding theory, and transportation systems. He is the recipient of the best paper award in the IEEE International Conference on Communications (ICC) in 2014.

Center for Cyber-Physical Systems and Internet of Things and Ming Hsieh Institute for Electrical Engineering Joint Seminar Series on Cyber-Physical Systems
Wed, Sep 13, 2017 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Nikos Arechiga, Toyota Research Institute
Talk Title: Scalable Automatic Reasoning in Model-Based Development
Abstract: Recent progress in vehicle autonomy and robotics has increased the importance of system assurance, ranging from safety to security concerns. These assurances require systems that are able to reason about large and complex system designs, often containing large lookup tables as well as AI components.
This talk presents a general-purpose technique that leverages machine learning to automatically learn logical antecedents and consequents to simplify a complex formal verification task.
We also describe a specialization of this technique that has been used within Toyota to reason about software with large lookup tables, including a public benchmark.
Finally, we look to the future and describe emerging research directions in automatic reasoning.
Biography: Dr. Nikos Arechiga graduated with a Ph. D. in Electrical and Computer Engineering at Carnegie Mellon working with Professor Bruce Krogh. His graduate work touched on automatic inference of barrier certificates to simplify proofs of safety as well as techniques for provably-correct controller synthesis.
He has been working at Toyota for two years, and has been involved with developing scalable reasoning techniques to address complex models with lookup tables, and is recently considering the problem of reasoning about AI components.

High-Level Program Optimizations for Data Analytics
Thu, Sep 14, 2017 @ 02:00 PM - 03:15 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Yufei Ding, University of California at Santa Barbara
Talk Title: High-Level Program Optimizations for Data Analytics
Abstract: Many modern applications, especially those data analytics, often spend a large number of cycles on unnecessary computations. To find a document most similar to a query document, for instance, these applications typically would need to examine hundreds of thousands of other documents (that are not the most similar ones) in the dataset. Such redundant computations have been hidden in the useful instructions of the applications and are elusive for traditional compiler-based code optimizations. My work harnesses these hidden but significant optimization opportunities by raising the level of program optimizations from implementations to algorithms, and from instructions to formulas.
Biography:
Yufei Ding will soon join the department of Computer Science, University of California at Santa Barbara as an assistant professor. She received her Ph.D. in the Computer Science from North Carolina State University, and B.S. and M.S. in Physics from University of Science and Technology of China and The College of William and Mary respectively. In 2012, she started her Ph.D. study in Computer Science. Her research interest resides at the intersection of Compiler Technology and (Big) Data Analytics, with a focus on enabling HighI-Level Program Optimizations for data analytics and other data-intensive applications. Yufei has been actively publishing in major venues in both computer systems and data analytics areas, such as ASPLOS, PLDI, OOPSLA, VLDB, ICDE, and ICML. She was the receipt of NCSU Computer Science Outstanding Research Award in 2016.

Internet of Skills-Enabled by 5G Decoupled Uplink & Downlink
Fri, Sep 15, 2017 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Mischa Dohler, King's College London, UK
Talk Title: Internet of Skills-Enabled by 5G Decoupled Uplink & Downlink
Abstract: With the emergence of an ultra-responsive and reliable 5G 'Tactile Internet,' advanced techniques in robotics and artificial intelligence, we advocate for the emergence of an 'Internet of Skills' which allows the "transmission of labor" globally. It will invoke an important shift from content-delivery to skillset-delivery networks, where engineers would service cars or surgeons performing critical operations anywhere on the planet. For this to work, however, we require some fundamental changes to wireless communications systems. This presentation will look at the disruptive technology approaches in wireless 5G, notably the impact of decoupling up and downlinks; as well as the impact it has on different industry verticals.
Biography: Mischa Dohler is full Professor in Wireless Communications at King's College London, driving cross-disciplinary research and innovation in technology, sciences and arts. He is the Director of the Centre for Telecommunications Research, co-founder of the pioneering smart city company Worldsensing, Fellow of the IEEE, the Royal Academy of Engineering and the Royal Society of Arts (RSA), and a Distinguished Member of Harvard Square Leaders Excellence.
He is a frequent keynote, panel and tutorial speaker, and has received numerous awards. He has pioneered several research fields, contributed to numerous wireless broadband, IoT/M2M and cyber security standards, holds a dozen patents, organized and chaired numerous conferences, was the Editor-in-Chief of two journals, has more than 200 highly-cited publications, and authored several books.
He acts as policy, technology and entrepreneurship adviser, examples being Richard Branson's Carbon War Room, former Minister David Willetts' 8 Great Technology Fund, UK Regulator Ofcom, UK Ministries, No 10, EPSRC ICT Strategy Advisory Team, European Commission, Tech London Advocate, ISO Smart City working group, and various start-ups.
He is also an entrepreneur; composer & pianist with 5 albums on iTunes and an artist-verified Spotify account; as well as fluent in 6 languages. He has talked twice at TEDx. He had coverage by national and international TV & radio, and his contributions have featured on the BBC, the Wall Street Journal and many others.
