Evaluate healthcare generative AI applications using LLM-as-a-judge on AWS
Machine Learning Blog
The article discusses a novel approach to evaluating healthcare generative AI applications using LLM-as-a-judge on AWS, focusing on generating radiology report impressions using Amazon Bedrock Knowledge Bases and RAG (Retrieval Augmented Generation) techniques.
- Introduced a comprehensive evaluation framework using five key metrics: correctness, completeness, helpfulness, logical coherence, and faithfulness
- Used MIMIC Chest X-ray dataset with 91,544 radiology reports for testing
- Leveraged Amazon Bedrock to compare different generative models like Anthropic's Claude and Amazon Nova
- Demonstrated high-performance scores across dev1 and dev2 datasets, with correctness and logical coherence metrics reaching 0.98-0.99
- Provides a systematic method to assess medical AI applications' accuracy, reliability, and clinical utility
The solution represents a significant advancement in maintaining reliability and accuracy of AI-generated medical content, with potential for broader healthcare applications.
