Abstract

The invention relates to a neural network training method and apparatus, an electronic device and a storage medium. The method comprises the steps of obtaining position information and category information of a target area in a sample image; cutting out at least one target area according to the position information of the target area; according to the category information, classifying the at leastone cut target area to obtain N types of sample image blocks; and inputting the N types of sample image blocks into a neural network for training. According to the neural network training method provided by the embodiment of the invention, the fine classification of the sample image blocks can be obtained, and the neural network is trained, so that the neural network can finely classify the images, the classification efficiency is improved, and the medical diagnosis accuracy is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a neural network training method and device, electronic equipment and storage media. Background technique [0002] Methods such as machine learning are widely used in the field of image processing, for example, they can be applied to the classification and image detection of ordinary images or three-dimensional images. For example, in the processing of medical images, machine learning methods can be used to determine disease categories and detect diseased areas. [0003] In the processing of medical images, the classification and detection of lung medical images (eg, lung computed tomography (CT, Computed Tomography)) play an important role in medical screening and diagnosis of pneumonia, lung cancer, etc. Lung cancer is one of the most common malignant tumors in my country, and its mortality rate ranks first in cancer deaths in both urban and rural areas, males a...
