Model monitoring is crucial for financial fraud classification models as it ensures their effectiveness after deployment. Financial services firms can use the WhyLabs Observatory to monitor their machine learning models, ensuring data security and privacy while scaling with the volume of processed data. The platform monitors data across various stages, detects anomalies, and sends notifications to help save time from debugging. By monitoring data and models, financial institutions can minimize losses from fraud by identifying data quality issues and changes in a data's distribution.
