Diagnosing Problems in ML Systems
Root Cause Analysis (RCA) is a systematic process for identifying the underlying cause of problems within machine learning systems. When a model degrades, produces errors, or behaves incorrectly, it’s crucial to address not just the symptoms but also the root issue.
A key technique involves repeatedly asking ‘why?’ to trace back the source of the problem.

Analyzing correlations and dependencies within data is essential for uncovering root causes.
Frequently asked questions
What is Root Cause Analysis?
Root Cause Analysis (RCA) is a structured approach to problem-solving that focuses on identifying the fundamental reason why an issue occurred, rather than just treating its symptoms.
How do I systematically conduct RCA for ML problems?
Start by gathering data – logs, metrics, predictions – and use structured methods like the ‘5 Whys’ or a Fishbone diagram to explore potential causes. Thoroughly check all components: data quality, model performance, infrastructure stability, and human factors.
What tools can help with RCA?
Various tools support RCA, including logging platforms (like Splunk), monitoring systems (e.g., Prometheus), statistical analysis software (R or Python), and visualization tools for creating diagrams.
