| Challenge: | Large Language Models (LLMs) often generate incorrect or outdated information, especially in low-resource settings or when dealing with private data. |
| Approach: | They propose a framework that iteratively refines the knowledge base based on expert feedback . they define a ReACT actor agent on each document to perform structured edits . |
| Outcome: | The proposed framework improves the quality and performance of the RAG system on low-resource programming problems, modified Python packages, and factual question-answering tasks. |

| Challenge: | Large Language Models (LLMs) have gained popularity due to their ability to generate human-like text and solve complex tasks. |
| Approach: | They propose an offline reinforcement learning technique that augments a semantic memory based on experiential learnings from past trials. |
| Outcome: | The proposed technique boosts Language agents’ performance by 4 % to 16.82 % over the raw GPT-4 baseline and performs on par with existing state-of-the-art prompt optimization techniques while requiring fewer LLM calls. |
