Abstract

The invention relates to a machine learning model training method and device and a face recognition method and device, and relates to the technical field of artificial intelligence. The training method comprises the following steps: extracting a feature vector of each image sample data by using a machine learning model, and determining a classification result of a target in each image sample dataaccording to each feature vector; judging whether the targets in the image sample data are classified into correct classifications or wrong classifications according to the labeling results and the classification results of the targets in the image sample data; under the condition that the target in any image sample data is classified into the wrong classification, reducing the first feature similarity between the image sample data and the correct classification, and increasing the second feature similarity between the image sample data and the wrong classification; and calculating a loss function for training a machine learning model according to all the reduced first feature similarities and the increased second feature similarities.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and in particular to a machine learning model training method, a machine learning model training device, a face recognition method, a face recognition device, electronic equipment, and a non-transitory computer-readable storage medium. Background technique [0002] In recent years, with the development of artificial intelligence technology, it is possible to identify objects in image data. For example, face recognition technology, as an application of target recognition, is widely used in scenarios related to identity verification, such as security, finance, and traffic. [0003] In related technologies, a machine learning model can be used to extract target features in image data, and then target recognition can be realized by calculating the similarity between features. Contents of the invention [0004] The inventors of the present disclosure have found the followin...
