Direct Prediction Set Minimization via Bilevel Conformal Classifier Training

Yuanjie Shi, Hooman Shahrokhi, Xuesong Jia +3

Conformal prediction (CP) is a promising uncertainty quantification framework which works as a wrapper around a black-box classifier to construct prediction sets (i.e., subset of c…

Uniformly consistent proportion estimation for composite hypotheses via integral equations: "the case of location-shift families"

Xiongzhi Chen

We consider estimating the proportion of random variables for two types of composite null hypotheses: (i) the means or medians of the random variables belonging to a non-empty, bou…

Uniformly consistent proportion estimation for composite hypotheses via integral equations: "the case of Gamma random variables"

Xiongzhi Chen

We consider estimating the proportion of random variables for two types of composite null hypotheses: (i) the means of the random variables belonging to a non-empty, bounded interv…
