An Effective Approach for Multi-label Classification with Missing Labels

no code implementations24 Oct 2022 Xin Zhang, Rabab Abdelfattah, Yuqi Song, XiaoFeng Wang

Through comprehensive experiments on three large-scale multi-label image datasets, i. e. MS-COCO, NUS-WIDE, and Pascal VOC12, we show that our method can handle the imbalance between positive labels and negative labels, while still outperforming existing missing-label learning approaches in most cases, and in some cases even approaches with fully labeled datasets.
