Model generation method and device, object classification method and device, electronic equipment and medium

The embodiment of the invention discloses a model generation method and device, an object classification method and device, electronic equipment and a storage medium. The model generation method comprises the steps of acquiring a to-be-trained classification model and a plurality of unlabeled objects, wherein the to-be-trained classification model comprises a classification prediction module and a loss function determination module; inputting each unlabeled object into a classification prediction module, and determining a pseudo classification result of each unlabeled object according to each unlabeled prediction result output by the classification prediction module; and inputting each unlabeled prediction result and the corresponding pseudo classification result into a loss function determination module, adjusting network parameters in a classification prediction module according to an output result of the loss function determination module, and generating an object classification model.
