Abstract: Provided are a label identification method and apparatus, a device, and a medium. The method includes: obtaining a target feature of a first image, in which the target feature characterizes a visual feature of the first image and a word feature of at least one label; and identifying a label of the first image from the at least one label based on the target feature. By characterizing the visual feature of the first image and the target feature of the word feature of the at least one label, the label of the first image is identified from the at least one label. Thus, identification accuracy of the label can be improved.

Abstract: The present disclosure relates to a multi-modal data retrieval method and apparatus, a medium, and an electronic device. The method includes: inputting target retrieval data into a first feature extraction network corresponding to a modality of the target retrieval data to acquire a data feature of the target retrieval data; inputting the data feature into a second feature extraction network corresponding to the modality of the target retrieval data to acquire a target retrieval feature corresponding to the target retrieval data, wherein second feature extraction networks respectively corresponding to modalities share a weight; and performing retrieval based on the target retrieval feature.
