Multi Objective Policy

Multi-objective policy optimization tackles the challenge of learning optimal policies when multiple, potentially conflicting objectives must be considered simultaneously. Current research focuses on developing robust algorithms, such as extensions of Proximal Policy Optimization (PPO) and the use of Pareto-based methods, to efficiently explore the trade-off space between these objectives and learn effective policies, often incorporating dimensionality reduction techniques to handle high-dimensional outcome spaces. This field is significant because it enables the development of more realistic and adaptable AI agents for complex real-world applications, ranging from personalized medicine and social program design to safe robotics and epidemic mitigation. The ability to balance competing objectives improves decision-making in scenarios where a single-objective approach is insufficient.
