New Bayesian Score Enhances Uncertainty Quantification Under Label Shift

Researchers have developed a new method called the Label-Shift-Adjusted Bayesian Score (LSA score) to improve uncertainty quantification in conformal prediction when label distributions change. Standard conformal prediction methods struggle with label shift, leading to inaccurate coverage. The LSA score addresses this by adjusting Bayesian scores using a posterior predictive tilting identity, which accounts for the shift in label distributions. This approach has shown promise in molecular property prediction, yielding shorter intervals with comparable coverage compared to existing methods. AI
