The five-step AI model validation process
Poff’s approach focuses on ensuring that AI models provide meaningful value to radiologists while minimizing drawbacks. The five key steps in his evaluation process include:
1. Performance statistics: This step involves assessing the accuracy and efficiency of the AI tool based on standard statistical metrics, ensuring that it meets baseline expectations for clinical use.
2. AI-enhanced detection rate: A crucial metric, this determines whether the AI tool helps radiologists detect findings that they might have otherwise missed, thereby improving diagnostic performance.
3. Wow cases: These are instances where the AI tool significantly enhances diagnostic capabilities, providing clear and impactful examples of its effectiveness.
4. AI pitfalls: Understanding the limitations and...
