Preference-conditioned Pixel-based AI Agent For Game Testing

no code implementations18 Aug 2023 Sherif Abdelfattah, Adrian Brown, Pushi Zhang

This paper addresses these limitations by proposing an agent design that mainly depends on pixel-based state observations while exploring the environment conditioned on a user's preference specified by demonstration trajectories.

A Robust Policy Bootstrapping Algorithm for Multi-objective Reinforcement Learning in Non-stationary Environments

no code implementations18 Aug 2023 Sherif Abdelfattah, Kathryn Kasmarik, Jiankun Hu

We propose a novel multi-objective reinforcement learning algorithm that can robustly evolve a convex coverage set of policies in an online manner in non-stationary environments.

Intrinsically Motivated Hierarchical Policy Learning in Multi-objective Markov Decision Processes

no code implementations18 Aug 2023 Sherif Abdelfattah, Kathryn Merrick, Jiankun Hu

In this work, intrinsically motivated reinforcement learning has been successfully deployed to evolve generic skill sets for learning hierarchical policies to solve multi-objective Markov decision processes.
