Zero-shot learning has gained popularity due to its potential to scale recognition models without requiring additional training data. This is usually achieved by associating categories with their semantic information like attributes. However, we believe that the potential offered by this paradigm is not yet fully exploited. In this work, we propose to utilize the structure of the space spanned by the attributes using a set of relations. We devise objective functions to preserve these relations in the embedding space, thereby inducing semanticity to the embedding space. Through extensive experimental evaluation on five benchmark datasets, we demonstrate that inducing semanticity to the embedding space is beneficial for zero-shot learning. The proposed approach outperforms the state-of-the-art on the standard zero-shot setting as well as the more realistic generalized zero-shot setting. We also demonstrate how the proposed approach can be useful for making approximate semantic inferences about an image belonging to a category for which attribute information is not available.

本研究针对零样本学习领域，将语义信息与属性相关联，通过使用一组关系来利用属性所张成的空间结构，提出了一种方法，在嵌入空间中保留这些关系的目标函数，从而导致嵌入空间的语义性的提高。通过在五个基准数据集上进行广泛的实验评估，我们证明了欲使嵌入空间语义化对零样本学习有益。该方法在标准零样本设置以及更加现实的广义零样本设置上均优于现有技术，同时演示了该方法如何对于对于某个没有属性信息的图像做出近似的语义推断是有用的。
