Multi-Agent Credit Assignment in Stochastic Resource Management Games
Mannion, Patrick; Devlin, Sam; Duggan, Jim; Howley, Enda (2017-08)Multi-Agent Systems (MAS) are a form of distributed intelligence, where multiple autonomous agents act in a common environment. Numerous complex, real world systems have been successfully optimised using Multi-Agent ... -
Policy Invariance under Reward Transformations for Multi-Objective Reinforcement Learning
Mannion, Patrick; Devlin, Sam; Mason, Karl; Duggan, Jim (2017)Reinforcement Learning (RL) is a powerful and well-studied Machine Learning paradigm, where an agent learns to improve its performance in an environment by maximising a reward signal. In multi-objective Reinforcement Learning ... -
Potential-Based Reward Shaping Preserves Pareto Optimal Policies
Mannion, Patrick; Devlin, Sam; Karl, Mannion; Duggan, Jim (2017-05)Reward shaping is a well-established family of techniques that have been successfully used to improve the performance and learning speed of Reinforcement Learning agents in singleobjective problems. Here we extend the ...
