Towards Effective Visual Representations for Partial-Label Learning

1 code implementation CVPR 2023 Shiyu Xia, Jiaqi Lv, Ning Xu, Gang Niu, Xin Geng

Under partial-label learning (PLL) where, for each training instance, only a set of ambiguous candidate labels containing the unknown true label is accessible, contrastive learning has recently boosted the performance of PLL on vision tasks, attributed to representations learned by contrasting the same/different classes of entities.

Progressive Purification for Instance-Dependent Partial Label Learning

no code implementations2 Jun 2022 Ning Xu, Biao Liu, Jiaqi Lv, Congyu Qiao, Xin Geng

Partial label learning (PLL) aims to train multiclass classifiers from the examples each annotated with a set of candidate labels where a fixed but unknown candidate label is correct.

One Positive Label is Sufficient: Single-Positive Multi-Label Learning with Label Enhancement

1 code implementation1 Jun 2022 Ning Xu, Congyu Qiao, Jiaqi Lv, Xin Geng, Min-Ling Zhang

To cope with the challenge, we investigate single-positive multi-label learning (SPMLL) where each example is annotated with only one relevant label, and show that one can successfully learn a theoretically grounded multi-label classifier for the problem.
