Production MLOps: Automated Concept Drift Detection and Retraining Loops

How to detect model decay in live production streams using Kolmogorov-Smirnov statistical tests and containerized Kubeflow pipelines.

### Preventing Machine Learning Decay in Production A machine learning model is only as good as the similarity between training data and live production inference streams. When market conditions, user demographics, or macro trends shift, models experience **Concept Drift** and **Data Drift**. #### Automated Drift Pipeline Architecture - Continuous telemetry logging of inference inputs and predictions. - Daily Statistical KS-tests against training distribution baselines. - Automated trigger of containerized Airflow / Kubeflow retraining jobs when p-value < 0.05.
