Outline of Research at the Start

Reinforcement Learning (RL) has demonstrated remarkable proficiency in various domains. However, there is still much to be done to enable RL agents to strategize long-term policies and navigate through environments with multiple reward signals.

This study aims to forge a comprehensive framework wherein RL agents can efficiently acquire modular hierarchical policies for multi-objective optimization challenges by leveraging the attention mechanism in Transformer networks. This will also enable the distillation of specialized solutions from overarching policies for specific application scenarios.
