Proxy-based loss for deep metric learning
Webb5 mars 2024 · Learning the distance metric between pairs of samples has been studied for image retrieval and clustering. With the remarkable success of pair-based metric learning losses, recent works have proposed the use of generated synthetic points on metric learning losses for augmentation and generalization. Webb31 mars 2024 · Existing metric learning losses can be categorized into two classes: pair-based and proxy-based losses. The former class can leverage fine-grained semantic relations between data points, but slows convergence in general due to …

Webb(MS) [18] losses were reformulated into proxy-based losses re-spectively in [15, 19, 20] by simply modifying the ways to con-struct a batch and to compute a similarity matrix. In this paper, we expand the multi-view approach into a proxy-based framework for deep metric learning by equating AGWEs with proxies. Based on the general pair weighting Webb31 mars 2024 · A novel Proxy-based deep Graph Metric Learning (ProxyGML) approach from the perspective of graph classification, which uses fewer proxies yet achieves better comprehensive performance and a novel reverse label propagation algorithm, by which a discriminative metric space can be learned during the process of subgraph classification.
