Talk Title: Tolerable Delay: Overcoming Intermittent Connectivity With Entity Centered Systems and Applications
Abstract: Reliance on Internet connectivity is detrimental where modern networking technology is lacking, power outages are frequent, or network connectivity is expensive, sparse, or non-existent (i.e., underserved urban communities, rural areas, natural disasters). Though there has been much research conducted around 5G and 6G serving as the conduit for connecting any and everything; scalability issues are a major concern and real-world deployments have been limited. Realization of the limitations resulting from reliance on Internet and cellular connectivity are prevalent in mHealth applications where remote patient monitoring has improved the timeliness of clinical decision making, decreased the length of hospital stays, and reduced mortality rates everywhere in the nation except in medically underserved and rural communities in the US like Appalachian Kentucky, where chronic disease is approximately 20% more prevalent than other areas. As an alternative, deploying resilient networking technology can facilitate the flow of information in resource-deprived environments to disseminate non-emergency, but life saving data. In addition, leveraging opportunistic communication can supplement cellular networks to assist with keeping communication channels open during high-use and extreme situations. This talk will discuss the pragmatic applications of designing opportunistic systems for particular entities (patients, citizens, etc.); specifically applied to healthcare and empowering low-cost smart cities, permitting any community to become smart and connected while simultaneously keeping network connectivity costs to a minimum.
Biography: Corey E Baker, PhD, is an Assistant Professor in the Department of Computer Science at the University of Kentucky (UK). His work centers around making data accessible in the midst of intermittent and limited connectivity while minimizing delay. He currently a directs the Network Reconnaissance (NetRecon) Lab [https://www.cs.uky.edu/~baker/research/ ] where his research investigates full stack systems for distributing, protecting, and authenticating data in opportunistic networking scenarios for rural remote patient monitoring, smart cities, and natural disasters to improve the livelihood of people. Professor Baker received a B.S. degree in Computer Engineering (CE) from San Jose State University (SJSU), a M.S. in Electrical and Computer Engineering (ECE) from California State University, Los Angeles (CSULA), and M.S. and Ph.D. degrees in CE from the University of Florida (UF). After the completion of his graduate studies, Baker was a University of California Presidents Postdoctoral Fellow in the ECE department at the University of California San Diego (UCSD) and a Visiting Scholar in the ECE department at the University of Southern California (USC). In 2019, Dr. Baker received the UK Inclusive Excellence Award [http://uknow.uky.edu/campus-news/office-institutional-diversity-awards-five-inclusive-excellence-awards?j=121590&sfmc_sub=129146772&l=18687_HTML&u=3630624&mid=10966798&jb=0]for his work in creating a graduate campus visit program and diversifying Computer Science and the College of Engineering at the doctoral level. Baker is currently the Region 6 (West Coast) Advisory Board Chairperson for the National Society of Black Engineers.

Talk Title: Fair, Representative, and Transparent Algorithms for Citizens' Assemblies
Series: CS Colloquium
Abstract: Globally, an alternative approach to democracy is gaining momentum: citizens' assemblies, in which randomly selected constituents discuss policy questions and propose solutions. Domain experts have two conflicting requirements on the selection of these assemblies: (1) assemblies should reflect the demographics of the population, and (2) all constituents should have equal chances of being selected. In this talk, I will describe work on designing and analyzing randomized selection algorithms that favorably trade off these objectives. I will share experiences with deploying these algorithms on our online platform Panelot and discuss what we learned from practitioners in the process of adoption. Finally, I will explore how these lessons sparked work on other aspects of citizens' assemblies, such as making the random selection process transparent and managing the discussions within the assembly.
This lecture satisfies requirements for CSCI 591: Research Colloquium
Biography: Paul Gölz is a postdoctoral researcher at the School of Engineering and Applied Sciences at Harvard. He received his Ph.D. in computer science from Carnegie Mellon University under the supervision of Ariel Procaccia. Paul studies democratic decision-making and the fair allocation of resources, using tools from algorithms, optimization, and artificial intelligence. Algorithms developed in his work are now deployed to select citizens' assemblies around the world and to allocate refugees for a major US resettlement agency.

Talk Title: Recent progress on singularity formation of 3D incompressible Euler and Navier-Stokes equations
Abstract: Abstract: Whether the 3D incompressible Euler and Navier equations can develop a finite time singularity from smooth initial data is one of the most challenging problems in fluid dynamics. In this talk, I will present a recent result with Dr. Jiajie Chen in which we prove finite time blowup of the 2D Boussinesq and 3D Euler equations with smooth initial data. There are several essential difficulties in establishing such blowup result. We overcome these difficulties by decomposing the solution operator into a leading order operator that enjoys sharp stability estimates plus a finite rank perturbation operator that can be estimated by using computer assisted proof. This enables us to establish nonlinear stability of the approximate self-similar profile and prove nearly self-similar blowup of the 2D Boussinesq and 3D Euler equations. I will also report some recent progress on potentially singular behavior of the 3D incompressible Navier-Stokes equations.
Biography: Thomas Yizhao Hou is the Charles Lee Powell professor of applied and computational mathematics at Caltech. His research interests include 3D Euler singularity, interfacial flows, multiscale problems, and adaptive data analysis. He received his Ph.D. from UCLA in 1987, and became a tenure track assistant professor at the Courant Institute in 1989, and a tenured associate professor in 1992. He moved to Caltech in 1993 and was named the Charles Lee Powell Professor in 2004. Dr. Hou has received a number of honors and awards, including Fellow of American Academy of Arts and Sciences in 2011, a member of the inaugural class of SIAM Fellows in 2009 and AMS Fellows in 2012, the SIAM Ralph E.

CS Colloquium: Emilio Ferrara (USC) - AI & Social Manipulation
Wed, Mar 29, 2023 @ 04:00 PM - 05:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Emilio Ferrara, USC Annenberg / CS
Talk Title: AI & Social Manipulation
Series: CS Colloquium
Abstract: In this talk, I will overview my decadelong journey into understanding the implications of online platform manipulation. I'll start from detecting malicious bots and other forms of manipulation including troll accounts, coordinated campaigns, and disinformation operations. The impact of my work will be corroborated with examples of findings enabled by our technology, e.g., our unveiling of the "Russian bots" operation prior to the 2016 U.S. Presidential election, which informed official Senate investigations and new regulations. I will then illustrate similar issues with the 2020 U.S. Election, as well as COVID-related conspiracies and public health misinformation. I'll conclude by discussing the ML tools we developed to model online mis/disinformation, reveal the malicious adversaries behind the curtains, and characterize their activity, behavior, and strategies, suggesting how they are changing the way researchers and study online platforms in the era of automation and artificial intelligence.
