Recent developments emphasize modular pipelines and better evaluation protocols, moving away from simple "retrieve-and-generate" approaches. 2. Core Advantages of Modern RAG
Techniques such as Concept Bottleneck Models (CBM-RAG) are being applied to improve the interpretability of retrieved evidence, particularly in specialized fields like medical report generation. 4. Challenges and Future Directions eccentric_rag_2020_remaster
