New metric 'prediction churn' highlights ML model instability

Researchers have identified a new metric called "cross-sample prediction churn" to measure the instability of machine learning models in scientific applications. This metric quantifies how predictions change when different subsets of training data are used. Standard techniques like deep ensembles do not reduce this churn, but two data-side methods, K-bootstrap bagging and the proposed twin-bootstrap method, show significant improvements. AI

    Reducing cross-sample prediction churn in scientific machine learning

    Scientific machine learning reports predictive performance. It does not report whether the same prediction would survive a different draw of training data. Across $9$ chemistry benchmarks, two classifiers trained on independent bootstraps of the same training set agree on aggrega…
