We have proposed a novel metric learning loss that takes advantages of both proxy- and pair-based losses

Abstract:

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 its high training complexity. In contrast, the latter class enables fast and reliable convergence, but cannot c...More
