Open set identification method and apparatus, electronic device, medium, and program product

Abstract

Embodiments of the present specification disclose an open set identification method and device, electronic equipment, medium and program product. The method comprises: obtaining to-be-identified data; inputting the to-be-identified data into an open set identification model, outputting a score corresponding to the to-be-identified data based on reference data of a specified target, and the score is used to represent the similarity between the to-be-identified data and the reference data; a loss function corresponding to the open set identification model is used to make the minimum value of a plurality of target scores in a target score set output by a neural network of the open set identification model greater than the maximum value of a plurality of non-target scores in a non-target score set output by the neural network, the target score is used to represent the similarity between data with the same target, and the non-target score is used to represent the similarity between data with different targets; and in the case that the score corresponding to the to-be-identified data is greater than a preset threshold, determining that the target corresponding to the to-be-identified data is the specified target.
