Method and device for training neural network

Abstract

The present disclosure relates to neural network training. The neural network training relates to a training method, a training device, and a system including the neural network. The neural network training includes extracting annotation data and first reliability values for first data using a neural network trained based on training data, selecting second data from among the first data based on the second data having second reliability values greater than or equal to a threshold value, expanding the training data based on the second data, and retraining the neural network based on the expanded training data.
