Reinforcement Teaching

no code implementations25 Apr 2022 Alex Lewandowski, Calarina Muslimani, Dale Schuurmans, Matthew E. Taylor, Jun Luo

To effectively learn such a teaching policy, we introduce a parametric-behavior embedder that learns a representation of the student's learnable parameters from its input/output behavior.

Disentangling Generalization in Reinforcement Learning

no code implementations29 Sep 2021 Alex Lewandowski, Dale Schuurmans, Jun Luo

The resulting environment, while simple, necessitates function approximation for state abstraction and provides ground-truth labels for optimal policies and value functions.
