Embodiment 1
[0050] Face recognition methods based on anti-noise meta-learning, such as figure 1 shown, including the following steps:
[0051] S1. Obtain a face dataset and its corresponding labels, where the labels include noise labels and clean labels;
[0052] S2. Preprocess the face data set: sample small batches of face data (X, Y) from the face data set, where X={x 1 ,…,x k } is k face data, Y={y 1 ,…,y k } is the corresponding noise label of each face data; for each noise label, multiple noise labels {Y′ are generated 1, …,Y′ M }, whose distribution is similar to Y, so that a set of generated noise labels Y′ m ={y' m1 ,…,y′ mk };
[0053] At the beginning of the training process, the face recognition model is not capable of face recognition. Therefore, all face data should be initialized with the same weight parameters for subsequent training.
[0054] S3. construct a face recognition model and its meta-learning model learning strategy, the input of the face recognition ...
