Learning to Assist Agents by Observing Them

no code implementations4 Oct 2021 Antti Keurulainen, Isak Westerlund, Samuel Kaski, Alexander Ilin

On the other hand, offline data about the behavior of the assisted agent might be available, but is non-trivial to take advantage of by methods such as offline reinforcement learning.

Behaviour-conditioned policies for cooperative reinforcement learning tasks

no code implementations4 Oct 2021 Antti Keurulainen, Isak Westerlund, Ariel Kwiatkowski, Samuel Kaski, Alexander Ilin

We suggest a method, where we synthetically produce populations of agents with different behavioural patterns together with ground truth data of their behaviour, and use this data for training a meta-learner.
