Challenge: Existing RAG systems that use pre-trained LLMs and retrievers often fail in specialized domains and applications.
Approach: They propose a self-aligned training framework that adapts general RAG models to specific domains solely through synthetic data.
Outcome: Experiments on specialized domain corpus, general LLM, and general retriever show that the self-aligned training framework outperforms human-annotated training data in specialized fields.
