Abstract:

Deep learning methods have made great progress in the field of computer vision, various deep convolutional neural networks have achieved good application effects in actual target detection, but the interpretability of the network is poor. The feature map is reversely mapped to the pixel space of the input image and the feature map of the network is visualized for analysis; under the framework of parallel vision research, the feature response of the network is analyzed with real and artificial insulator image samples, the network parameters are adjusted according to the visualization results. The results show that the artificial samples with different proportions, angles and positions have different effects on the accuracy of the network, the characteristic response of the network is also different. The structure and parameters of the network are adjusted according to the visualization results of the feature graph, which improves the performance of the network.

Key words: parallel vision, convolutional neural network, visualization, characteristic response
