In a typical production-grade ML system, the actual model code accounts for only a very small fraction of the overall codebase, with systems engineering code for data collection, feature engineering, monitoring, serving infrastructure, and the like constituting the majority.

UnverifiedThe artifacts of an ML system are not just code, but also include data, feature processing logic, and model weights, and drift in any one of these can lead to degraded production performance.74% similarUnverifiedA model that runs locally does not mean it can run in production; when deploying ML systems, managing memory is as important as managing code.71% similarUnverifiedA complete ML system typically includes data collection and feature storage, model training pipelines, offline evaluation and A/B testing, model registration and version management, online serving deployment, and performance monitoring and alerting.70% similarUnverifiedA model's training objective is to generate code that looks correct, not code that is maintainable over the long term in a specific system.69% similarUnverifiedThe systematic process for debugging a non-converging model is to first verify on a very small data subset whether the model can overfit; if it cannot overfit even on small data, it indicates a bug in the model or training code.68% similar
