We are heartbroken by the loss of Luca Trevisan, who served as senior scientist at the Institute from 2014 to 2019.
One might recall that one of the inaugural programs hosted by the Simons Institute, back in Fall 2013, was Real Analysis in Computer Science. In the decade since, the field has cultivated influential new themes such as global hypercontractivity and spectral independence, incorporated methods based on high-dimensional expanders and stochastic calculus, and also enabled striking applications in hardness of approximation, Markov chain analysis, and coding theory. All this progress makes this an excellent time to reconvene a program on this topic.
Greetings from Berkeley! Summer programs are in full swing at the Simons Institute and it’s been great to see and catch up with many friends from near and far.
In April 2023, the Simons Institute hosted a workshop on Multigroup Fairness and the Validity of Statistical Judgment, the latest in a series of workshops and clusters we’ve organized on the theme of algorithmic fairness, as part of our Algorithms, Society, and the Law initiative.
In this episode of Polylogues, Simons Institute Director Shafi Goldwasser sits down with workshop leader Omer Reingold (Stanford) to explore the key themes of the workshop.
As the prevalence of machine learning expands across diverse domains, the role of algorithms in influencing decisions that significantly impact our lives becomes increasingly important. Concerns regarding the fairness of algorithmic decisions have spurred the proposal and investigation of the framework of multigroup fairness, which provides a mathematical foundation for assessing fairness across numerous overlapping subpopulations.
In this talk in the Simons Institute’s recent workshop on Multigroup Fairness and the Validity of Statistical Judgment, Rachel Lin (University of Washington) elucidates the close relationships among several recently proposed notions of multigroup fairness, namely, multi-accuracy, multi-calibration, and outcome indistinguishability, and concepts of pseudorandomness from complexity theory and cryptography, specifically leakage simulation in cryptography, weak regularity in complexity theory, and graph regularity in graph theory. By exploring these connections, Lin demonstrates that ideas in either area can lead to improvement in the other.
Dear friends,
Greetings from the Simons Institute, where our Summer 2023 research programs are ramping up.
One of the programs this summer is Analysis and TCS: New Frontiers. Back in Fall 2013, Real Analysis in Computer Science was one of the first programs hosted by the Simons Institute, making the current program a beautiful way to mark 10 years of programs at the Institute.
Eighty outstanding researchers, innovators and communicators from around the world have been elected as the newest Fellows of the Royal Society, the UK’s national academy of sciences and the oldest science academy in continuous existence.
Greetings from the Simons Institute, where we are wrapping up our Spring 2023 research program on Meta-Complexity and an extended reunion of the Satisfiability program. It has been a semester full of scientific discoveries, chances to make new friends and reconnect with old ones.
In his recent Theoretically Speaking public lecture, U.S. International Mathematical Olympiad team coach Po-Shen Loh (Carnegie Mellon) spoke on educational adaptation to generative AI.
The Simons Institute’s Breakthroughs lecture series highlights major research advances in theoretical computer science, as they happen. This spring, Raghu Meka presented joint work with Zander Kelley on one of the most important open problems in additive combinatorics.
