Generalized Zero-Shot Learning (GZSL) targets recognizing new categories bylearning transferable image representations . Existing methods find that, by aligning image representations with corresponding semantic labels, thesemantic-aligned representations can be transferred to unseen categories . In this paper, we propose a novel Dual-ContrastiveEmbedding Network (DCEN) that simultaneously learns task-specific and task-independent knowledge via semantic alignment and instance discrimination . DCEN leverages task labels to cluster representations of the samesemantic category by cross-modal contrastive learning and exploringsemantic-visual complementarity. DCEN obtainsaveraged a 4.1% improvement on four public benchmarks, according to the paper . Compared to high-level seen category supervision, this instancediscrimination
