RAG Outperforms DFT for Robust AI Knowledge Systems
This study evaluates Retrieval-Augmented Generation (RAG) and Domain-Specific Fine-Tuning (DFT) for building AI-driven knowledge systems using LLMs. RAG consistently outperformed DFT in ROUGE, BLEU, and a custom Coverage Score, showing better factual accuracy and reduced hallucination. DFT showed a slight edge in METEOR, indicating more creative output but at the cost of factual consistency, especially when integrated with RAG. The findings suggest RAG is a more practical and resource-efficient approach for reliable domain-adapted knowledge systems.

The Role of Context Filtering in RAG
Our RAG implementation included a crucial context filtering step based on cosine similarity thresholds. This dynamic filtering, which discards irrelevant context items, proved essential in optimizing the model's input size (max 4096 tokens for LLaMA-2-7b) and improving answer quality. It effectively reduced noise and ensured that only the most semantically similar information was provided to the LLM, directly contributing to the observed reduction in hallucination and superior factual accuracy.
Optimal Similarity Threshold: 0.5 | Max Context Tokens: 4096
