MLOps
Machine Learning Lifecycle, Model Registries & Drift Detection
MLOps brings DevOps rigor to Machine Learning. It standardizes model training, experiment tracking, versioned feature storage, automated inference deployment, and continuous monitoring for data and concept drift.
Standard Delivery Lifecycle
Sequential stages, responsibilities, and tooling required to implement MLOps.
Data Versioning & Feature Store
Tracking dataset lineage and feature store availability for training and serving.
Pipeline Orchestration & Experiment Tracking
Reproducible model training pipelines with hyperparameter metrics.
Model Registry & Packaging
Validated model staging with governance approvals and containerization.
Serving & Drift Observability
Real-time or batch inference with latency and statistical drift metrics.
Real-World Challenges & Solutions
Practical issues encountered in production, root-cause analyses, and concrete code/configuration fixes.
Model prediction accuracy plummets in production while inference latency and error rates appear completely healthy.
Incoming production feature distributions shift compared to the historical training dataset (covariate shift).
Deploy continuous drift detection using Evidently AI or Prometheus metrics to compute Kolmogorov-Smirnov statistical divergence on input tensors, automatically triggering retraining pipelines.
