DESCRIPTION:Title: Uncertainty quantification for black-box models with con
 ditional guarantees\n\nAbstract:\n\nA central problem in the uncertainty q
 uantification literature is designing methods that are both distribution-f
 ree and individualized to the test sample at hand. Prior work has shown th
 at it is impossible to achieve finite-sample conditional validity without 
 modelling assumptions. Thus\, canonical methods in\, e.g.\, the conformal 
 inference literature\, typically only issue marginal guarantees over a ran
 dom draw of the test covariates. In this talk\, I will outline a framework
  that bridges this gap by recasting the conditional objective as a set of 
 robustness criteria over a class of covariate shifts. By relaxing the targ
 et class of covariate shifts\, I will define a spectrum of problems that r
 ange between marginal and exact conditional validity and give methods that
  provide precise guarantees in between these extremes. This framework has 
 broad applications and I will show how it can be used to construct predict
 ion sets around the outputs of black-box regression models and filter out 
 false information from the responses of large language models. This talk i
 s based on joint work with John Cherian and Emmanuel Candès.\n\n🔗 Zoom: ht
