ERM-based PU classifiers designed for case-control sampling deteriorate under single-sample scenarios, requiring a change in the empirical risk definition; a single-sample analogue of the non-negative risk classifier is introduced and shown to differ notably when many positives are labeled.

A two-step framework combines stacked hurdle random forest models for local severity prediction with semi-parametric spatio-temporal modeling to reconstruct large-scale disease dynamics from imperfect indicators, demonstrated on sugar beet yellows in France.

Single-sample versus case-control sampling scheme for Positive Unlabeled data: the story of two scenarios

Predicting disease severity and large-scale spread from coupled severity measurements and imperfect indicators: Application to beet yellows
