Feature Store
Domain: MLOps
🎯 Motivation
A centralized store for features (input variables). Ensures consistency between training and serving.
📋 Concrete Example
Feature store: user_age, purchase_history, click_rate. Training uses these features. Serving uses the same features. Consistent.
🔗 Analogy
A pantry in a restaurant - ingredients are stored centrally. Both the prep kitchen (training) and the cooking line (serving) use the same pantry. A feature store ensures consistency.
