Feature stores are essential for production machine learning, addressing the critical problem of feature definition drift between training and serving environments. This drift can silently degrade model performance, particularly for high-risk predictions, as models are trained on one data distribution and scored on another. To ensure point-in-time correctness, feature stores provide historical feature values, preventing target leakage and maintaining model integrity. AI
IMPACT Ensures model reliability by preventing training-serving skew and target leakage, crucial for accurate real-time predictions.
