A common assumption in machine learning and statistics is the existence of training data comprising independent observations from the entire distribution of relevant data. In practice, data deviates from this assumption in various ways. Data might be biased samples from the distribution of interest, due to systematic selection bias, societal biases, incorrect experimental design, or legal restrictions that might prevent the use of all available data. Moreover, observations might be collected on a social network, a spatial or a temporal domain and may thus not be independent but intricately dependent. Finally, data might be affected by the choices made by other learning agents who are learning and making decisions in the same environment where our data is collected and must be acted upon. In the presence of these deviations from the standard i.i.d. model naively trained models fail. In this talk, we overview recent work with various collaborators suggesting avenues to address the resulting challenges through a combined approach involving tools from truncated statistics, high-dimensional probability, statistical physics, and game theory.

Meredith Ringel-Morris, Microsoft Research
Meredith Ringel-Morris is a computer scientist conducting research in the areas of human-computer interaction (HCI), computer-supported cooperative work (CSCW), social computing, and accessibility. Her current research focus is on accessibility, particularly on the intersection of accessibility and social technologies. In the past, her main research focus was social and collaborative web search. Ringel-Morris has also studied other classes of collaboration technologies, including gesture systems and tabletop computing systems. Ringel-Morris is a Sr. Principal Researcher and Research Manager for the Ability research group at Microsoft Research. She is also an affiliate Professor in The Paul G. Allen School of Computer Science & Engineering and in The Information School at the University of Washington, where I participate in the dub research consortium.

Joan Feigenbaum, Yale
Joan Feigenbaum is the Grace Murray Hopper Professor of Computer Science at Yale University, where she also holds a courtesy appointment as Professor of Economics. She received a BA in Mathematics from Harvard and a Ph.D. in Computer Science from Stanford. Between finishing her Ph.D. in 1986 and starting at Yale in 2000, she was with AT&T, where she participated broadly in the company's Information-Sciences research agenda, e.g., by creating a research group in Algorithms and Distributed Data, of which she was the manager in 1998-99. Professor Feigenbaum's research interests include security, privacy, anonymity, and accountability; Internet algorithmics; and computational complexity. While at Yale, she has been a principal in several high-profile activities, including the DHS-funded Pri-Fi Project, the DARPA-funded DISSENT project, and the NSF-funded PORTIA project. Her many service contributions to the research community include Program Chair of Crypto '91, Editor-in-Chief of the Journal of Cryptology (1997-2002), Program Co-Chair of the ACM Conference on Electronic Commerce (2004), Program Chair of the ACM Symposium on Theory of Computing (2013), Department Chair of the Yale Computer Science Department (July 2014 through June 2017), General Chair of the inaugural ACM Symposium on Computer Science and Law (2019), and ACM Vice President (July 2020 through June 2022). Professor Feigenbaum is an Amazon Scholar, a Fellow of the ACM, a Fellow of the AAAS, a Member of the Connecticut Academy of Science and Engineering, and a Connecticut Technology Council Woman of Innovation. In 1998, she was an invited speaker at the International Congress of Mathematicians. In May 2020, she won the Test-of-Time Award from the IEEE Symposium on Security and Privacy for her 1996 paper (with Matt Blaze and Jack Lacy) entitled "Decentralized Trust Management."
