Metric Conformal Prediction via the Conditional Expected Local Radius
Rui Qiu, Fang Yao, Zhou Yu
We introduce the conditional expected local radius (CELR) and develop a new conformal prediction method for non-Euclidean responses in general metric spaces. CELR measures local co…

Marginal Coordinate Test for Fréchet Regression with Random Objects
Jiaye Chen, Rui Qiu, Roulin Wang +1
We develop a marginal coordinate test for regression with Euclidean predictors and a random-object response in a separable metric space. The goal is to test whether a predictor pro…

Semi-supervised Fréchet Regression
Rui Qiu, Zhou Yu, Zhenhua Lin
This paper explores the field of semi-supervised Fréchet regression, driven by the significant costs associated with obtaining non-Euclidean labels. Methodologically, we propose tw…
