The model was fine last month, now it’s making bad predictions and no one knows why
The situation this course is for
You deployed a machine learning model that passed all tests, but within weeks, performance decayed due to shifting input distributions, unlogged schema changes, or feedback loops. No automated monitoring caught it early. Now, every Monday, you spend hours tracing whether the issue is data quality, concept drift, or feature leakage. The stakeholder report gets rewritten weekly. The fix feels reactive, not systematic.
Who this is for
Backend engineers maintaining AI/ML systems in production who face unexplained model decay and lack a repeatable diagnosis and correction workflow
Who this is not for
Data scientists who only train models offline, researchers focused on novel architectures, or managers without hands-on deployment responsibilities
What you walk away with
- Detect model drift within 24 hours of onset using lightweight, deployable monitoring scripts
- Diagnose root cause, data drift, concept drift, or system feedback loop, with a structured triage checklist
- Implement automated retraining triggers that preserve model stability without overfitting
- Document model behavior changes in a way that satisfies audit and uptime requirements
- Reduce time spent on model firefighting by at least 60% across your current projects

If nothing changes
Without a structured approach, model decay will continue to cause recurring downtime, erode stakeholder trust, and increase operational load, especially as AI systems scale across MongoDB's infrastructure.
How this compares to the alternatives
Unlike generic ML operations courses, this program focuses exclusively on the operational reality of backend engineers: detecting and fixing model decay in systems already in production, with no reliance on idealized data pipelines or research environments.
