论文摘要

零射对象识别或零拍学习旨在将对象识别能力转移到语义相关类别(例如细粒动物或鸟类)之间。但是,不同细颗粒物体的图像往往仅表现出细微的外观差异,这将严重恶化零拍物体识别。为了减少细颗粒对象中的多余信息,在本文中,我们建议学习无冗余的特征,以供广义零拍学习。我们通过将原始视觉特征投影到新的(无冗余)特征空间,然后限制这两个特征空间之间的统计依赖性来实现动力。此外,我们需要预测的功能来保持甚至加强无冗余功能空间中的类别关系。这样,我们可以从视觉功能中删除冗余信息,而不会丢失歧视性信息。我们在四个基准数据集上广泛评估了性能。结果表明,与最先进的艺术相比,我们基于无冗余功能的广义零射击学习(RFF-GZSL)方法可以获得竞争成果。

Zero-shot object recognition or zero-shot learning aims to transfer the object recognition ability among the semantically related categories, such as fine-grained animal or bird species. However, the images of different fine-grained objects tend to merely exhibit subtle differences in appearance, which will severely deteriorate zero-shot object recognition. To reduce the superfluous information in the fine-grained objects, in this paper, we propose to learn the redundancy-free features for generalized zero-shot learning. We achieve our motivation by projecting the original visual features into a new (redundancy-free) feature space and then restricting the statistical dependence between these two feature spaces. Furthermore, we require the projected features to keep and even strengthen the category relationship in the redundancy-free feature space. In this way, we can remove the redundant information from the visual features without losing the discriminative information. We extensively evaluate the performance on four benchmark datasets. The results show that our redundancy-free feature based generalized zero-shot learning (RFF-GZSL) approach can achieve competitive results compared with the state-of-the-arts.
