Quarterly Theory Workshop: Algorithmic Fairness

June 8, 2018
Northwestern University

Registration deadline: June 8, 2018

As algorithmic systems have increasingly been deployed to make consequential decisions, it is becoming urgent that we grapple with the problem of (un)fairness and discrimination. These are delicate issues — to think rigorously about them, we first need to figure out how to formally define what we want, and then reason about how we might go about achieving our goals algorithmically — and what tradeoffs we will have to manage. This workshop focuses on recent advances in the theory of algorithmic fairness: both on foundational definitional questions, and on algorithmic techniques. The speakers are Nicole Immorlica (MSR), Jon Kleinberg (Cornell), Omer Reingold (Stanford), and Aaron Roth (U. of Pennsylvania).
The technical program of this workshop is organized by Aaron Roth and Jason Hartline.

Parameterized Approximation Algorithms Workshop

July 9, 2018
Prague, Czechia

Submission deadline: April 20, 2018
Registration deadline: May 31, 2018

Two standard approaches to handle hard (typically NP-hard) optimization problems are to develop approximation and parameterized algorithms. For the former, the runtime should be polynomial in the input size, but the computed solution may deviate from the optimum. For the latter, the optimum solution should be computed, but any super-polynomial runtime should be isolated to some parameter of the input. Some problems however are hard to approximate on one hand, and on the other it is also hard to obtain parameterized algorithms for some given parameter. In this case one may still hope to obtain parameterized approximation algorithms, which combine the two paradigms, i.e. the computed solution may deviate from the optimum and the runtime should have super-polynomial dependence only in some given parameter. Recently there has been a great deal of development in proving the existence or non-existence of parameterized approximation algorithms, and the aim of this workshop is to bring together active researchers of this emerging field, so that they may share their results and insights.

Conference on High Dimensional Combinatorics

April 22-26, 2018

Registration deadline: April 13, 2018

Combinatorics in general, and the theory of expander graphs in particular, have been fruitful areas of interaction between pure and applied mathematics. In recent years, a “high dimensional” combinatorial theory has emerged. Aside from its intellectual appeal, this theory has a great potential for various applications in mathematics and computer science. This theory calls for a cooperation of experts in these different fields. The conference will bring leading experts in these topics.
