4 best practices for RAG:
53.3% AI professionals plan to deploy LLM in the next 6 months.
RAG, or Retrieval Augmented Generation, is a technique designed to overcome limitations in Large Language Models (LLMs) by enhancing contextual understanding and providing grounded responses. LLMs, trained on vast parameter sets, possess the capacity to respond to a wide array of questions.
However, when it comes to fact-based inquiries, they may generate responses based on their training data.
Public-facing LLMs are evolving to avoid furnishing current factual information.
For instance, when prompted with the question, \’Who is the president of the United States?\’
ChatGPT 3.5 responded, \’As of my last knowledge update in January 2023, I do not have the most current information on the President of the United States.\’
RAG addresses this issue by extending the knowledge base of LLMs, incorporating databases, social media feeds, manuals, or documents. Some advantages of RAG include:
Cost-Effectiveness: Unlike retraining LLMs, which is expensive and challenging to maintain, RAG implementation is quick and resource-efficient.
Enhanced User Confidence: RAG implementation typically includes displaying the information source along with LLM responses. This transparency boosts user confidence and reduces the likelihood of hallucination.
Best practices for RAG implementation include:
1. Data Source Quality: Ensure reliable data sources for RAG, as the output is contingent on the quality of the data. Establish a process for periodic data quality improvement.
2. Continuous Updates: Regularly update data used by RAG to ensure the timeliness of responses. Depending on the use case, updates can occur in batches or real-time.
3. Regular Result Evaluation: Similar to other machine learning models, regularly evaluate and update RAG results to correct any errors and enhance accuracy.
4. Productize through MLOps: Incorporate RAG into the MLOps workflow from the outset to ensure continuous optimization and currency. Avoid treating RAG as an afterthought or a bolted-on component.
