Value function interference and greedy action selection in value-based multi-objective reinforcement learning

no code implementations9 Feb 2024 Peter Vamplew, Cameron Foale, Richard Dazeley

Multi-objective reinforcement learning (MORL) algorithms extend conventional reinforcement learning (RL) to the more general case of problems with multiple, conflicting objectives, represented by vector-valued rewards.

Utility-Based Reinforcement Learning: Unifying Single-objective and Multi-objective Reinforcement Learning

no code implementations5 Feb 2024 Peter Vamplew, Cameron Foale, Conor F. Hayes, Patrick Mannion, Enda Howley, Richard Dazeley, Scott Johnson, Johan Källström, Gabriel Ramos, Roxana Rădulescu, Willem Röpke, Diederik M. Roijers

Research in multi-objective reinforcement learning (MORL) has introduced the utility-based paradigm, which makes use of both environmental rewards and a function that defines the utility derived by the user from those rewards.

An Empirical Investigation of Value-Based Multi-objective Reinforcement Learning for Stochastic Environments

no code implementations6 Jan 2024 Kewen Ding, Peter Vamplew, Cameron Foale, Richard Dazeley

One common approach to solve multi-objective reinforcement learning (MORL) problems is to extend conventional Q-learning by using vector Q-values in combination with a utility function.

A Conceptual Framework for Externally-influenced Agents: An Assisted Reinforcement Learning Review

no code implementations3 Jul 2020 Adam Bignold, Francisco Cruz, Matthew E. Taylor, Tim Brys, Richard Dazeley, Peter Vamplew, Cameron Foale

In this work, while reviewing externally-influenced methods, we propose a conceptual framework and taxonomy for assisted reinforcement learning, aimed at fostering collaboration by classifying and comparing various methods that use external information in the learning process.

A Demonstration of Issues with Value-Based Multiobjective Reinforcement Learning Under Stochastic State Transitions

no code implementations14 Apr 2020 Peter Vamplew, Cameron Foale, Richard Dazeley

We report a previously unidentified issue with model-free, value-based approaches to multiobjective reinforcement learning in the context of environments with stochastic state transitions.
