Abstract

The embodiment of the invention discloses a face recognition model training method, device and equipment. The method comprises the steps of obtaining a training sample comprising face key points; dividing the training sample into a plurality of sub-images; determining the category to which any sub-image belongs according to key points included in the sub-images, and generating a plurality of image subsets corresponding to a plurality of different categories; determining local feature vectors corresponding to the plurality of image subsets by adopting an initial model, and fusing the local feature vectors to generate a global feature vector corresponding to the training sample; and performing classification training on the initial model according to the global feature vector to generate an available target model. Therefore, for the target model obtained by training, the similarity between the image subset contained in each to-be-identified image and the corresponding region of the to-be-confirmed image can be quantified during use.

Description

technical field [0001] This specification relates to the field of Internet technologies, and in particular, to a training method, apparatus and device for a facial recognition model. Background technique [0002] With the great progress of deep learning, facial recognition technology has made remarkable progress and is widely used in practical applications of identity authentication, such as mobile phone unlocking, gate authentication, payment and other scenarios. However, since the large-scale training of facial recognition models has always been a black-box system, the interpretability is poor, especially for close relatives or people with similar faces, the differences are quite subtle, and there is no quantitative interpretable basis. [0003] Based on this, a training scheme for facial recognition models with high interpretability of recognition results is required. SUMMARY OF THE INVENTION [0004] One or more embodiments of this specification provide a facial recog...
