CLAREL: Classification via retrieval loss for zero-shot learning [article]

Boris N. Oreshkin and Negar Rostamzadeh and Pedro O. Pinheiro and Christopher Pal
2020 arXiv   pre-print
We find that on the generalized zero-shot classification task CLAREL consistently outperforms the existing approaches on both datasets.  ...  On top of that, we provide a probabilistic justification for a metric rescaling approach that solves a very common problem in the generalized zero-shot learning setting, i.e., classifying test images from  ...  Table 1 : 1 Generalized zero-shot Top-1 classification accuracy.  ...

2020 2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)  
We evaluate our approach on two fine-grained zero-shot datasets: CUB and FLOWERS.  ...  The key novelty of this paper is that it shows that using per-image semantic supervision leads to substantial improvement in zero-shot performance over using class-only supervision.  ...  Table 3 : 3 Generalized zero-shot Top-1 classification accuracy.  ...
