Researchers have developed RoBAS, a novel framework for Robust Bayes-Assisted Shrinkage, designed to improve the efficiency of prediction sets in conformal prediction. This method combines Bayesian modeling with frequentist guarantees, adapting to the reliability of the Bayesian working model's prior information. RoBAS offers two instantiations: one using a heavy-tailed Bayesian model and another employing an empirical Bayes shrinkage score. Evaluations on tabular and image regression tasks demonstrate that RoBAS performs competitively with existing scores under standard conditions and significantly reduces interval widths when data distributions shift between training, calibration, and test sets.
