Factorizable joint shift revisited

arXiv:2601. 15036v4 Announce Type: replace Abstract: Factorizable joint shift (FJS) represents a type of distribution shift (or dataset shift) that comprises both covariate and label shift.

General Quantification of Covariate and Concept Shifts

arXiv:2609. 11918v1 Announce Type: new Abstract: Generalization under distribution shift remains a core challenge in modern machine learning, yet existing learning bound theory is limited to narrow, idealized settings and is non-estimable from samples.

Importance Weighting for Unlabeled-unlabeled Learning under Distribution Shift

This paper introduces a method for adapting unlabeled‑unlabeled (UU) learning to distribution shifts by applying importance weighting. The approach estimates weights from UU data in both training and test distributions to minimize test risk, enabling handling of various learning scenarios—including PU and noisy‑label learning—without assuming specific shift types. Experiments on real‑world datasets confirm the method’s effectiveness.

Robust Conformalized Selection with Noisy Responses

arXiv:2607. 22985v1 Announce Type: cross Abstract: Conformalized selection has been widely applied to select high-quality candidates from large datasets with rigorous uncertainty quantification, such as reliable labeling, drug discovery, and the alignment of large language models.
