From Local Geometry to Global Pseudo Labeling for Robust Positive Unlabeled Learning under Covariate Shift 事件

From Local Geometry to Global Pseudo Labeling for Robust Positive Unlabeled Learning under Covariate Shift arXiv:2605.31187v1 Announce Type: new Abstract: Detecting covariate shift is critical for building reliable vision systems. While most prior work focuses on improving robustness to shift, explicitly detecting covariate shift remains underexplored. Existing approaches typically rely on fully supervised training, requiring labeled examples from both original and shifted distributions, which
