Use drift and/or stability reports to decide when to promote a challenger to the
champion.
The stability report shows the deployment stability. Model promotion is
indicated by a dashed vertical line and a change in the plot symbols from a
filled dot for the champion to an empty dot for a challenger. For example, the
Random Forest model was promoted on July 16.
The drift report shows the champion model drift. The drift report shows the
current champion as well as the champion for the report time period. For
example, the promotion of Random Forest occurs on July 16, 2023 17:50. The
champion for times before 17:50 was the CART model.
