Practice diagnosing and stabilizing a time-series ML forecasting pipeline after online accuracy drops. The solution covers data ingestion, feature generation, training, serving, time-aware evaluation, segment metrics, baselines, online canaries, remediation, monitoring, and ML release governance.

Question

Your time-series machine-learning pipeline has become unstable and prediction accuracy is dropping.

Describe how you would diagnose the root cause across data ingestion, feature generation, and model-serving layers.

Explain the evaluation framework, sampling strategy, and metrics you would use to quantify performance regressions.

Outline the technical fixes and process changes you would implement to restore stability and prevent future issues.
