Guerra", "Yen-Yun Yu" ], "categories": [ "cs.CV" ], "abstract": "While much of recent study in semi-supervised learning (SSL) has achieved strong performance on single-label classification problems, an equally important yet underexplored problem is how to leverage the advantage of unlabeled data in multi-label classification tasks. To extend the success of SSL to multi-label classification, we first analyze with illustrative examples to get some intuition about the extra challenges exist in multi-label classification. Based on the analysis, we then propose PercentMatch, a percentile-based threshold adjusting scheme, to dynamically alter the score thresholds of positive and negative pseudo-labels for each class during the training, as well as dynamic unlabeled loss weights that further reduces noise from early-stage unlabeled predictions. Without loss of simplicity, we achieve strong performance on Pascal VOC2007 and MS-COCO datasets when compared to recent SSL methods.", "revisions": [ { "version": "v1", "updated": "2022-08-30T01:27:48.000Z" } ], "analyses": { "keywords": [ "multi-label semi-supervised classification", "percentile-based dynamic thresholding", "percentmatch", "achieve strong performance", "single-label classification problems" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
