Learning Attentive Pairwise Interaction for Fine-Grained Classification (API-Net)

Peiqin Zhuang, Yali Wang, Yu Qiao

Introduction:

In order to effectively identify contrastive clues among highly-confused categories, we propose a simple but effective Attentive Pairwise Interaction Network (API-Net), which can progressively recognize a pair of fine-grained images by interaction. We aim at learning a mutual vector first to capture semantic differences in the input pair, and then comparing this mutual vector with individual vectors to highlight their semantic differences respectively. Besides, we also introduce a score-ranking regularization to promote the priorities of these features. For more details, please refer to our paper.
