Conformalized Safe Feasible Sets in Uncertain Decision Systems
Yajie Bao, Yinjie Min, Haojie Ren +1
Safety-critical decision systems often require a downstream optimizer to choose from an unknown feasible set determined by an unobserved label . Given a context , the goal is…
Enhanced localized conformal prediction with imperfect auxiliary information
Yinjie Min, Liuhua Peng, Changliang Zou
There is growing interest in constructing conformal prediction sets that provide approximate or asymptotic conditional coverage guarantees, capturing local data heterogeneity. Howe…
Efficient Federated Estimation and Inference for High-Dimensional Tail Index Regression
Haoyu Geng, Liuhua Peng, Changliang Zou +1
Tail index regression studies how covariates affect tail heaviness in heavy-tailed data. In many applications, data are distributed across heterogeneous sources, where direct pooli…
A Unified Theory of Conditional Coverage in Conformal Prediction with Applications
Yinjie Min, Liuhua Peng, Changliang Zou
Conformal prediction provides prediction sets with finite-sample marginal coverage, but many applications require coverage guarantees that adapt to individual test points, a subpop…
Generalized Boundary FDR Control under Arbitrary Dependence: An Approach on Closure Principle
Yifan Zhang, Wentao Zhang, Changliang Zou +1
False discovery rate (FDR) is a cornerstone of modern multiple testing. However, it often fails to guarantee the reliability of "marginal" discoveries that lie at the boundary of t…
Stable Localized Conformal Prediction via Transduction
Yinjie Min, Liuhua Peng, Changliang Zou
Existing evaluations of conformal prediction, such as prediction efficiency and test-conditional coverage, are defined in expectation over the calibration data. In practice, when o…
