论文摘要
现有的大多数少数学习方法描述了与二进制标签的图像关系。但是,由于缺乏决策平稳性,这种二元关系不足以教导网络复杂的现实关系。此外,当前的几杆学习模型仅通过关系标签捕获相似性,但它们不暴露于与对象相关的类概念,这可能会由于未充分利用可用类标签而导致的分类性能。用一些实际例子以及老虎与其他动物的比较来了解老虎的概念。因此,我们假设实际上相似性和阶级概念学习必须同时进行。有了这些观察结果,我们研究了当前几次学习方法中简单级别建模的基本问题。我们重新考虑班级概念之间的关系,并提出一种新颖的绝对叠加学习范式,以充分利用标签信息来完善图像表示并纠正受监督和无监督和无监督的情景中的关系理解。我们提出的范式提高了公开可用数据集上几种最先进模型的性能。
The majority of existing few-shot learning methods describe image relations with binary labels. However, such binary relations are insufficient to teach the network complicated real-world relations, due to the lack of decision smoothness. Furthermore, current few-shot learning models capture only the similarity via relation labels, but they are not exposed to class concepts associated with objects, which is likely detrimental to the classification performance due to underutilization of the available class labels. To paraphrase, children learn the concept of tiger from a few of actual examples as well as from comparisons of tiger to other animals. Thus, we hypothesize that in fact both similarity and class concept learning must be occurring simultaneously. With these observations at hand, we study the fundamental problem of simplistic class modeling in current few-shot learning methods. We rethink the relations between class concepts, and propose a novel Absolute-relative Learning paradigm to fully take advantage of label information to refine the image representations and correct the relation understanding in both supervised and unsupervised scenarios. Our proposed paradigm improves the performance of several the state-of-the-art models on publicly available datasets.
