model assertion
What It Means
Model assertions are automated checks that monitor your AI system by examining what goes in and what comes out to detect when something is going wrong. Think of them as quality control sensors that continuously watch your AI's behavior and flag potential problems before they impact your business. They're custom rules you set up to catch errors, biases, or unexpected outputs based on your specific use case.
Why Chief AI Officers Care
These assertions act as an early warning system that can prevent costly AI failures, regulatory violations, and reputational damage by catching problems in real-time rather than after customers complain. They're essential for maintaining trust and compliance, especially in regulated industries where you need to demonstrate ongoing monitoring and control of AI systems. Without them, you're essentially flying blind and may only discover AI malfunctions after significant business impact.
Real-World Example
A bank using AI for loan approvals sets up model assertions to check that approval rates don't suddenly drop below 10% or spike above 60% in any given day, and that the system isn't systematically denying loans to specific demographic groups. When the assertion triggers because approval rates hit 75% one afternoon, it automatically alerts the team who discovers a data pipeline error was feeding incorrect credit scores to the model.
Common Confusion
People often confuse model assertions with general system monitoring or think they're the same as accuracy metrics. Unlike basic performance monitoring, assertions are specifically designed business rules that check for domain-specific problems, not just whether the system is running or how accurate predictions are on average.
