Concept Drift: Monitoring Model Quality in Streaming Machine Learning Applications

Показать описание
Most machine learning algorithms are designed to work on stationary data. Yet, real-life streaming data is rarely stationary. Models lose prediction accuracy over time if they are not retrained. Without model quality monitoring, retraining decisions are suboptimal and costly. Here, we review the monitoring methods and evaluate them for applicability in modern fast data and streaming applications.

Dears, I am looking for an algorithms that can be used to monitor the health of a productive model build based on supervised data .How can I define the time when the model must be updated or retrained with the new available data. The input data of the productive model is changing by nature with time and other factors .

You could have used a script to compensate for the tough to understand accent you have.
