Talk Title: Drawing Inspiration from Collective Motion in Nature
Abstract: Biological systems are frequently categorized as complex systems due to their capabilities of generating spatio-temporal structures from apparent random decisions. In spite of research on analyzing biological systems, we lack a quantifiable framework for measuring their complexity. To fill this gap, we develop a new paradigm to study a collective group of N agents moving and interacting in a three-dimensional space. Our paradigm helps to identify the spatio-temporal states of the motion of the group and their associated transition probabilities. This framework enables the estimation of the free energy landscape corresponding to the identified states. Based on the energy landscape, we quantify missing information, emergence, self-organization and complexity for a collective motion. We show that the collective motion of the group of agents evolves to reach the most probable state with relatively lowest energy level and lowest missing information compared to other possible states. Our analysis demonstrates that the natural group of animals exhibit a higher degree of emergence, self-organization and complexity over time. Consequently, this algorithm can be integrated into new frameworks to engineer collective motions to achieve certain degrees of emergence, self-organization and complexity.
Biography: Hana Koorehdavoudi is a PhD candidate in Mechanical Engineering at the University of Southern California. She received her BS degree in Mechanical Engineering from the Sharif University of Technology in 2010. Her research interests include cellular motility, biological swarm dynamics, applied mathematics to design and modeling of dense networks of bacteria with a potential application for therapeutic purposes (e.g. drug delivery in inaccessible regions of the human body).

Seminar - From Harmonic Telegraph to Cellular Phones
Tue, Aug 23, 2016 @ 10:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Bishnu S. Atal, University of Washington
Talk Title: From Harmonic Telegraph to Cellular Phones
Abstract: It all started with two patents issued to Alexander Graham Bell in March 1876 and the world changed forever. Vast distances began to shrink. Soon, nobody was isolated. The invention produced a new industrial giant whose research laboratories supported the best in scientific research and engineering leading to major technical advances of the twentieth century. The desire for communication, anytime, anywhere spread fast; stationary phones connected by wires started fading away, replaced by 'cellular phones' ('smart phones') reflecting the cell structure of the wireless medium. This talk will provide a history of the telephones, starting from Alexander Graham Bell's 'harmonic telegraph' in 1876 to modern cellular phones.
Biography: Bishnu S. Atal is an Affiliate Professor in the Electrical Engineering Department at the University of Washington, Seattle, WA. He retired in March 2002 after working for more than 40 years at Lucent Bell Labs, and AT&T Labs
Dr. Atal's pioneering research on speech coding for providing natural-sounding speech over digital devices has resulted in standards that lie at the heart of practically every mobile phone in use today. His work has enabled wireless networks to use less spectrum space and fewer towers to aid in the mass deployment of digital cellular systems. He demonstrated during the 1960s that Linear Predictive Coding 'LPC' could represent the varying characteristics of human voice and encode the speech signal at a fraction of conventional bit rates . LPC quickly became the basis for military communication standards. He introduced the CELP method in 1985, and it is now used in practically all digital cellular speech standards as well as standards for digital voice communication over the Internet.
Dr. Atal is a member of the U.S. National Academy of Sciences. His many honors include the Thomas Edison Patent Award (1994) , the New Jersey Hall of Fame Inventor of the Year Award (2000), the IEEE Morris N. Liebmann Memorial Field Award (1986), the Benjamin Franklin Medal in Electrical Engineering (2003), and the 2013 IEEE Jack S. Kilby Signal Processing Medal.
Bishnu resides in Mukilteo, Washington. He has two daughters, Alka and Namita, two granddaughters, Jyotica and Sonali, and two grandsons, Ananth and Niguel.

(Network) Massive MIMO – Analysis for a Local Area Scenario
Thu, Aug 25, 2016 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Stefan Dierks, Technical University Munich
Talk Title: (Network) Massive MIMO -“ Analysis for a Local Area Scenario
Abstract: The performance of centralized and distributed deployments of massive MIMO in an office building is analyzed both with and without cooperation. It is shown that using twice as many base station antennas as data streams provides most of the massive MIMO benefits. A simple transmission scheme achieves user fairness and operates close to a capacity upper bound. The tradeoff between performance and cost for backhauling is evaluated by comparing cooperation of distributed base stations with a single central deployment. First results on the equivalent isotropically radiated power (EIRP) of massive MIMO arrays are presented.
Biography: Stefan Dierks received the B.Sc. and the M.Sc. equivalent Diplom-Ingenieur degree in Electrical Engineering from Technical University Munich (TUM) in 2009 and 2011 respectively. During his studies he visited Universidad Nacional del Sur in BahÃa Blanca, Argentina for one semester. Since 2011 he is working towards his Ph.D. degree at the Institute for Communications Engineering at TUM under the supervision of Prof. Kramer. His research interests include massive MIMO, LTE, 5G, EIRP of MIMO arrays, and Interference Alignment.

NL Seminar
Fri, Aug 26, 2016 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Ke Tran , USC/ISI Intern
Talk Title: Unsupervised learning linguistic structures with deep neural networks
Series: NL Seminar
Abstract: We present a general framework for unsupervised learning that combines probalistic graphical models with the power of deep nets. We employ a neuralized expectation miminization algorithm for learning. We apply this framework for unsupervised sequential tagging and show some interesting results.
Biography: Ke is a PhD candidate at University of Amsterdam. He is interning at ISI, working with Yonatan Bisk, Ashish Vaswani, Kevin Knight, and Daniel Marcu. His research focuses on deep learning and machine translation.
