Minimum Volume Optimal Transport for Multivariate Conformal Prediction
Chuchen Zhang, Haojie Ren, Zhaojun Wang +2
Optimal transport (OT) enables multivariate conformal prediction (CP) to construct flexible prediction sets that reflect the underlying complex distributional geometry while retain…
Interval Localization for Multiple Change-points with Error Rate Control
Zijian Wei, Yajie Bao, Haojie Ren +1
Interval localization in multiple change-point detection aims to identify intervals containing true change-points while controlling false discoveries. We formulate this task as a m…
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…
Shape-Adaptive Conditional Calibration for Conformal Prediction via Minimax Optimization
Yajie Bao, Chuchen Zhang, Zhaojun Wang +2
Achieving valid conditional coverage in conformal prediction is challenging due to the theoretical difficulty of satisfying pointwise constraints in finite samples. Building upon t…
