Shaping Visual Representations with Attributes for Few-Shot Learning
share
Few-shot recognition aims to recognize novel categories under low-data regimes. Due to the scarcity of images, machines cannot obtain enough effective information, and the generalization ability of the model is extremely weak. By using auxiliary semantic modalities, recent metric-learning based few-shot learning methods have achieved promising performances. However, these methods only augment the representations of support classes, while query images have no semantic modalities information to enhance representations. Instead, we propose attribute-shaped learning (ASL), which can normalize visual representations to predict attributes for query images. And we further devise an attribute-visual attention module (AVAM), which utilizes attributes to generate more discriminative features. Our method enables visual representations to focus on important regions with attributes guidance. Experiments demonstrate that our method can achieve competitive results on CUB and SUN benchmarks. Our code is available at https://github.com/chenhaoxing/ASL.
