Abstract

The invention relates to a neural network training method and device and an image processing method and device. The training method comprises the following steps: carrying out classification processing on a target image in a training set through a neural network to obtain a prediction classification result of the target image; and training the neural network according to the prediction classification result, the initial category label and the correction category label of the target image. According to the embodiment of the invention, the training process of the neural network can be supervisedby initializing and correcting the category label, and the training process and the network structure are simplified.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a neural network training method and device, and an image processing method and device. Background technique [0002] With the continuous development of artificial intelligence technology, machine learning (especially deep learning) has achieved good results in many fields such as computer vision. The current machine learning (deep learning) has a strong dependence on large-scale accurately labeled data sets, but it is very time-consuming and expensive to collect large-scale accurately labeled data sets. A new branch of machine learning seeks to train networks on imprecisely labeled 'noisy data' to improve network generalization and reduce the cost of collecting the required data. [0003] In related technologies, it is usually necessary to pre-assume the noise distribution of the label, add additional supervision data, or design an auxiliary network to achieve networ...
