Our latest whitepaper on Retrieval-Augmented Generation (RAG) offers insights into the advancements and challenges of Retrieval-Augmented Generation (RAG) within the industry. It provides an analysis of industry demands, current methodologies, and the obstacles in developing and evaluating RAG. Additionally, our whitepaper aims to facilitate strategy development and knowledge exchange about practical use cases across various industrial sectors. The whitepaper is the result of extensive studies and discussions conducted with our internal teams and industry partners. It highlights RAG as a cost-effective technique that has significantly improved the trustworthiness and control of Large Language Model (LLM) applications over the past year.

Key Takeaways

1. RAG Industrialization - Landscape & Strategy

• Discover the essential role of RAG solutions in sustainable industrial knowledge retrieval and question-answering.
• Understand how trustworthiness, consistency, controllability, and cost efficiency make RAG indispensable.
• Learn about advanced techniques like HyDE and adaptive retrieval that can enhance quality while addressing resource constraints.
• Early identification of challenges is crucial for prioritizing development tasks and minimizing risks related to quality, robustness, and costs in deploying RAG solutions.

2. RAG Recipes for Real-World Challenges

• Learn about five practical recipes that address challenges such as limited initial evaluation data, complex contexts, and domain-specific conventions. 
• Enhance relevance through metadata, SQL queries, task-specific finetuning, and multimodal RAG-augmented reasoning.
• Improving retrieval quality is key for creating reliable and robust RAG solutions. Start with cost-effective strategies like metadata filtering and hybrid search, then progress to advanced agentic approaches for further enhancement.

3. A Deep Dive into RAG Evaluation & Metrics

• Gain insights into the complex task of assessing RAG systems, which requires evaluating the interplay among questions, contexts, ground truth, and responses.
• Understand the importance of metrics like context relevance, recall, precision, and answer correctness.
• Although emerging LLM frameworks support RAG evaluation, no single framework covers all aspects comprehensively. The industry needs a standardized framework to ensure consistent quality, reliability, and scalability assessments throughout RAG development and benchmarking.
