Abstract

The present disclosure relates to a sample image determination method and device, electronic equipment, and a storage medium, wherein the method includes: using a first preset number of classifiers to respectively predict each sample image, and obtain the corresponding Prediction vectors: respectively converting the prediction vectors corresponding to the sample images into probability vectors; determining the difficult sample images from the sample images according to the probability vectors corresponding to the sample images. The sample image determination provided by the present disclosure can accurately and quickly extract difficult sample images from multiple sample images without manual intervention, which can save human resources.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a method and device for determining a sample image, electronic equipment, and a storage medium. Background technique [0002] Recently, deep learning has been widely used in video image, speech recognition, natural language processing and other related fields. Convolutional neural network is an important branch of deep learning. Due to its strong fitting ability and end-to-end global optimization ability, the prediction accuracy of video image classification tasks is greatly improved after applying convolutional neural network. Although the current image classification model has a certain ability to classify images, there are still a large number of wrongly predicted sample images. How to further optimize the image classification model has become a problem that needs to be solved. [0003] Hard sample images tend to play a larger role than easy sample image...
