Adaptive cognitive orthotics: combining reinforcement learning and constraint-based temporal reasoning

Published: 04 July 2004 Publication History

Abstract

Reminder systems support people with impaired prospective memory and/or executive function, by providing them with reminders of their functional daily activities. We integrate temporal constraint reasoning with reinforcement learning (RL) to build an adaptive reminder system and in a simulated environment demonstrate that it can personalize to a user and adapt to both short- and long-term changes. In addition to advancing the application domain, our integrated algorithm contributes to research on temporal constraint reasoning by showing how RL can select an optimal policy from amongst a set of temporally consistent ones, and it contributes to the work on RL by showing how temporal constraint reasoning can be used to dramatically reduce the space of actions from which an RL agent needs to learn.
