A new research paper introduces the concept of "prior laundering," a technique where learned generative priors are used for ill-posed Bayesian inverse problems. This method involves using an archive of legacy reconstructions when ground truth data is scarce, such as in seismic or medical imaging. The paper argues that this process can lead to inherited, undetectable overconfidence in the posterior uncertainty, as the reported uncertainty may reflect the archive's beliefs rather than the data's actual resolvability. The authors recommend reporting which directions measurements resolve to distinguish data-supported confidence from inherited beliefs. AI
