The Day Synthetic Data Turned Poisonous: Inside Model Collapse
A recent article highlights the critical difference between testing an ML model in isolation and testing the entire production system. It details a scenario where a recommendation model, performing well in offline evaluations, failed under real-world traffic due to infrastructure collapse in the feature retrieval pipeline. The piece advocates for using synthetic data to stress-test the complete ML system, including data retrieval, feature computation, and serving infrastructure, before deployment to identify and resolve potential bottlenecks that offline evaluations miss.
