Webpability considerably. For example, contrastive loss [6] and binomial deviance loss [40] only consider the cosine sim-ilarity of a pair, while triplet loss [10] and lifted structure loss [25] mainly focus on the relative similarity. We pro-pose a multi-similarity loss which fully considers multiple similarities during sample weighting.

Web24 de jun. de 2024 · In this paper, we present a hierarchical multi-label representation learning framework that can leverage all available labels and preserve the hierarchical relationship between classes. We introduce novel hierarchy preserving losses, which jointly apply a hierarchical penalty to the contrastive loss, and enforce the hierarchy constraint.
