A new paper published on arXiv explores the reliability of Predictive Bayesian Inference (PBI). The research demonstrates that PBI's posterior concentration is dependent on the forward predictive model used, which also entirely dictates the uncertainty quantification. The study highlights that if the predictive model fails to capture all relevant data features, the coverage of PBI credible sets can be significantly reduced, potentially approaching zero. AI
