This video demonstrates how to perform RAG (Retrieval-Augmented Generation) evaluations on Amazon Bedrock to measure and improve AI model performance for business applications like customer-facing chatbots 0:00-0:37.
Key Takeaways:
• Evaluations are essential for ensuring AI accuracy and tracking improvements as you iterate your systems 0:00-0:37
• Amazon Bedrock provides a fully managed service with access to leading models from various providers 0:39-0:59
• Setting up evaluations requires three S3 buckets: context/knowledge, test prompts, and evaluation results storage 3:46-4:17
• The tutorial shows creating a hotel policy knowledge base and testing it with sample questions against different models 9:00-12:24
• Results can be compared between models to determine which performs better on metrics like correctness and helpfulness 16:38-17:26
The evaluation framework enables data-driven decisions when implementing AI systems in production environments.

If you can't measure it, you can't improve it. Today, I'm going to show you how to do model evaluations, specifically rag evaluations. For example, if you're running a business and you have a chatbot communicating with your customers, you want to make sure that the information that is giving the customers is accurate and it can cause big problems if it's not. And also, as you iterate on your AI stack, you want to make sure you're heading in the right direction. You want to make sure you're actually improving. And again, having these benchmarks in place and being able to actually see the improvement in the metrics as you iterate is important. And I'm going to show you all of this step by step on Amazon Bedrock. Amazon Bedrock is a fully managed service where you can choose from the best mod…
