Causal Inference in Complex Networks
Thu, Oct 26, 2017 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Negar Kiyavash, University of Illinois at Urbana-Champaign
Talk Title: Causal Inference in Complex Networks
Abstract: One of the paramount challenges of this century is that of understanding complex, dynamic, large-scale networks. Such high-dimensional networks, including social, financial, and biological networks, cover the planet and dominate modern life. In this talk, we propose novel approaches to inference in such networks, for both active (interventional) and passive (observational) learning scenarios. We highlight how timing could be utilized as a degree of freedom that provides rich information about the dynamics. This information allows resolving direction of causation even when only a subset of the nodes is observed (latent setting). In the presence of large data, we propose algorithms that identify optimal or near-optimal approximations to the topology of the network.
Biography: Negar Kiyavash is Willett Faculty Scholar at the University of Illinois and a joint Associate Professor of Industrial and Enterprise Engineering (IE) and Electrical and Computer Engineering (ECE). She is the director of Advance Data Analytics Program in IE and is further affiliated with the Coordinated Science Laboratory (CSL) and the Information Trust Institute. She received her Ph.D. degree in ECE from the University of Illinois at Urbana-Champaign in 2006. Her research interests are in design and analysis of algorithms for network inference and security. She is a recipient of NSF CAREER and AFOSR YIP awards and the Illinois College of Engineering Dean's Award for Excellence in Research.

Fred S. Grodins Keynote Lecture
Thu, Oct 26, 2017 @ 03:00 PM - 04:00 PM
Alfred E. Mann Department of Biomedical Engineering
Conferences, Lectures, & Seminars
Speaker: Na Ji, PhD, Associate Professor Departments of Physics and Molecular Cell Biology, University of California, Berkeley
Talk Title: Probing neural circuits with shaped light
Series: Annual Grodins Keynote Lecture
Abstract: To understand computation in the brain, one needs to understand the input-output relationships for neural circuits and the anatomical and functional relationships between individual neurons therein. Optical microscopy has emerged as an ideal tool in this quest, as it is capable of recording the activity of neurons distributed over millimeter dimensions with sub-micron spatial resolution. I will describe how we use concepts in astronomy and optics to develop next-generation microscopy methods for imaging neural circuits at higher resolution, greater depth, and faster speed. By shaping the wavefront of the light, we have achieved synapse-level spatial resolution through the entire depth of primary visual cortex, optimized microendoscopes for imaging deeply buried nuclei, and developed a video-rate (30 Hz) volumetric imaging method. We apply these methods to understanding neural circuits, using the mouse primary visual cortex as our model system.
Biography: Na Ji studied chemistry and physics as an undergraduate in the University of Science and Technology of China, then pursued her graduate degree at the University of California Berkeley. In 2006, she moved to Janelia Research Campus, Howard Hughes Medical Institute, where she worked with Eric Betzig on improving the speed and resolution of in vivo brain imaging. She started her own group in Janelia in 2011, where, in addition to imaging technology development, her lab applies the resulting techniques to outstanding problems in neurobiology. Na Ji, PhD, is currently at Associate Professor in the Department of Physics and Department of Molecular Cell Biology at the University of California, Berkeley.
Host: Department of Biomedical Engineering; Reception will be held at the Andrus Gerontology Courtyard from 4:00 pm to 5:30 pm.

CAIS Seminar: Dr. Sze-Chuan Suen (University of Southern California) - A POMDP Model for Drug Resistant Tuberculosis Screening
Thu, Oct 26, 2017 @ 04:00 PM - 05:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Dr. Sze-Chuan Suen, University of Southern California
Talk Title: A POMDP Model for Drug Resistant Tuberculosis Screening
Series: Center for AI in Society (CAIS) Seminar Series
Abstract: This lecture satisfies requirements for CSCI 591: Research Colloquium.
Patients with drug resistant disease may need different treatment than those with drug-sensitive disease. However, identifying these patients may be difficult since tests to determine disease strain may be time consuming or costly. In this project, we develop a model using POMDP and simulation techniques to identify when and which first-line tuberculosis patients are most likely at risk for drug resistance and should be screened to reduce costs and increase health outcomes.
Biography: Sze-Chuan Suen received her PhD in the department of Management Science and Engineering from Stanford University in 2016. Her research interests include developing applied mathematical models to identify epidemiological trends and evaluate health policies to support informed decision-making. Her research draws from techniques in simulation, dynamic systems modeling, optimization, and decision analysis.
