Title: AI-Powered Group Decision Making

Abstract: Making fair, efficient, and trustworthy collective decisions for groups of agents has become a significant concern among the public in the past decade in a wide range of scenarios, such as elections, public policy making, recommender systems, crowdsourcing, and blockchain governance. Unfortunately, in many cases, the architectures and mechanisms are suboptimal and far below people's expectations.

In this talk, I will present our work on the theory and practice of building AI-powered group decision making systems to improve fairness, efficiency, and trustworthiness in the processes of modeling, learning, and aggregation of preferences. Our approach is highly multi-disciplinary and is based on leveraging principles, ideas, and methodologies from disciplines including behavioral sciences, economics, political science, statistics, and computer science.
