Large Language Models for Structured Task Decomposition in Reinforcement Learning Problems with Sparse Rewards
This in-depth analysis explores how Large Language Models (LLMs) can revolutionize Reinforcement Learning (RL) by addressing the critical challenge of sparse rewards. Our framework introduces a novel teacher-student paradigm, where LLMs guide RL agents through complex tasks by decomposing them into manageable, sequential subgoals, drastically improving learning efficiency and generalization.

Faster Convergence in RL Training
Our LLM-guided framework significantly accelerates RL training, achieving over 90% faster convergence compared to traditional methods in sparse-reward environments, drastically reducing the time and computational resources required for agents to master complex tasks.
Enterprise Process Flow
Our proposed teacher-student framework leverages LLMs for initial subgoal generation. An offline surrogate model then learns to mimic this behavior, providing scalable guidance during online RL training. This decouples the agent from expensive LLM queries, ensuring efficient and robust learning.

MiniGrid Benchmark: Generalization
Summary: The framework was tested on MiniGrid, a benchmark with procedurally generated environments requiring strong generalization. This setup validated the robustness of LLM-guided subgoal generation in unseen tasks.
Challenges:
- Sparse rewards leading to inefficient exploration.
- Difficulty in generalizing to new, unseen environment layouts.
- Computational cost of continuous LLM queries during training.
Solution: Leveraged LLMs to decompose complex tasks into sequential subgoals. Implemented a scalable surrogate model to mimic LLM behavior offline, reducing computational overhead. Introduced three subgoal types: positional, representation-based, and language-based, enhancing learning efficiency and adaptability.
Results:
- Achieved over 90% faster training convergence.
- Outperformed recent teacher-student methods for sparse-reward environments.
- Demonstrated enhanced exploration and generalization across diverse MiniGrid tasks.
