UnverifiedCommon practices for monitoring drift include statistically tracking changes in the distribution of input features (such as the PSI metric), tracking the distribution of online prediction results, and regularly sampling for manual review.68% similarVerifiedCommonly used statistical methods for detecting drift include PSI (Population Stability Index), KL divergence, and the Kolmogorov-Smirnov test.60% similarUnverifiedDuring evaluation, per-case experiment diffs should be examined rather than only looking at changes in aggregate scores, in order to pinpoint regressions to specific cases60% similar
