AUL is a better optimization metric in PU learning

no code implementations1 Jan 2021 Shangchuan Huang, Songtao Wang, Dan Li, Liwei Jiang

Recent works try to recover the unbiased result by estimating the proportion of positive samples with mixture proportion estimation (MPE) algorithms, but the model performance is still limited and heavy computational cost is introduced (particularly for big datasets).

Improving Positive Unlabeled Learning: Practical AUL Estimation and New Training Method for Extremely Imbalanced Data Sets

no code implementations21 Apr 2020 Liwei Jiang, Dan Li, Qisheng Wang, Shuai Wang, Songtao Wang

Secondly, we propose ProbTagging, a new training method for extremely imbalanced data sets, where the number of unlabeled samples is hundreds or thousands of times that of positive samples.
