• Compositional zero-shot learning (CZSL) aims to recognize novel concepts from known subconcepts. However, it is still challenging since the intricate interaction between subconcepts is entangled with their corresponding visual features, which affects the recognition accuracy of concepts. Besides, the domain gap between training and testing data leads to the model poor generalization. In this article, we tackle these problems by exploring partial semantic consistency (PSC) to eliminate visual deviation to guarantee the discrimination and generalization of representations. Considering the complicated interaction between subconcepts and their visual features, we decompose seen images into visual elements according to their labels and obtain the instance-level subdeviations from compositions, which is utilized to excavate the category-level primitives of subconcepts. Furthermore, we present a multiscale concept composition (MSCC) approach to produce virtual samples from two aspects, which augments the sufficiency and diversity of samples so that the proposed model can generalize to novel compositions. Extensive experiments indicate that our method significantly outperforms the state-of-the-art approaches on three benchmark datasets.
