The invention discloses a teacher-student architecture noise-label-containing image classification method based on feature space reforming, and belongs to the field of noise label learning and image classification. The success of deep learning mainly depends on a large-scale tagged data set. Most of data sets are manually labeled, so that the labeling accuracy is difficult to guarantee. Therefore, noise tags are inevitable in a real-world data set. Due to the strong learning ability of the deep neural network, the noise label is very easy to over-fit, and the model performance is reduced. In order to solve the problem, the invention provides a teacher-student structure based on feature space reformation, and the teacher-student structure is used for learning noise labels. A teacher model is trained to correct noise labels for student models. A feature space reforming mechanism is applied to guide a student model to carry out self-learning, so that the student model learns more meaningful information.
