In AI systems, features often become hidden assets. They encode historical patterns, domain knowledge, business rules, time windows, entity behavior, and model assumptions. Without a feature store or feature registry, teams may duplicate feature code across projects, produce inconsistent training and inference logic, and lose track of which features were used in which model version. FeatureHub provides a structured layer for registering feature definitions, storing metadata, tracking versions, and reusing feature outputs across training, inference, evaluation, and decision workflows. It can help forecasting systems reuse time based features, scoring models reuse entity features, and decision engines reuse rule derived or state derived features. The module is most valuable when paired with AutoFeature Kits, LabelWorks, SchemaBridge, and model evaluation tools. Users should still define governance rules for feature naming, ownership, freshness, leakage checks, and compatibility. Production use may require integration with storage systems, access control, online feature serving, and monitoring. FeatureHub should be treated as a foundation for disciplined feature operations rather than a complete enterprise feature platform by itself. Show more
