VerifiedCommon methods for detecting data drift include the KS test, PSI (Population Stability Index), and sliding-window-based statistical monitoring.66% similarUnverifiedCalibrating a threshold involves two steps: first, randomly sample document chunk pairs from the index to measure the noise floor; then, use a labeled set of positive and negative samples to fit a threshold that meets the desired precision.63% similarUnverifiedCommon 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.61% similarUnverifiedMost existing LLM-assisted screening evaluation methods rely on traditional metrics such as accuracy, which can be misleading on highly class-imbalanced systematic review datasets.60% similar
