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.

Operational Philosophy:Code + Data = Model. Traditional DevOps versions code; MLOps must version the code, the datasets, and the hyperparameter configurations together.

Troubleshooting & Battle-Tested Fixes

Real-World Challenges & Solutions

Practical issues encountered in production, root-cause analyses, and concrete code/configuration fixes.

Symptom / Error Indicator

Model prediction accuracy plummets in production while inference latency and error rates appear completely healthy.

Root Cause

Incoming production feature distributions shift compared to the historical training dataset (covariate shift).

Resolution Procedure

Deploy continuous drift detection using Evidently AI or Prometheus metrics to compute Kolmogorov-Smirnov statistical divergence on input tensors, automatically triggering retraining pipelines.

Long-term Prevention: Log 100% of inference inputs and outputs asynchronously to a data lake for continuous distribution validation.

Architecture Checklist

Recommended Best Practices

Foundational rules for sustainable, resilient, and secure operations.

Never deploy a model without an automated benchmark against a baseline test set.
Version data artifacts using cryptographic hashes (DVC or LakeFS).
Decouple model training compute from production inference clusters.
Implement shadow deployments (mirror traffic) before releasing new model weights to users.
