Advances in Human-Informed Decision-Making: Representations, Inference, and experiments
Abstract
Advances in technology and interface design are enabling heterogenous group activities that include both human and computer participants. The need to support these highly diverse interactions brings new and significant challenges to AI; how to design efficient representations for describing online group interactions; how to design incentives that keep participants motivated and productive; and how to provide useful, non-intrusive information to the system designers and to users to explain group behavior and to help them decide whether and how to intervene.
I will describe ongoing work in my lab that addresses these challenges using novel applications of reinforcement learning and probabilistic modeling. I will demonstrate t these approaches in two projects: enhancing volunteer engagement in citizen science, and modeling students' activities in mixed reality simulations.
