Abstract

The invention discloses an image processing-oriented convolutional neural network vertical segmentation method, which belongs to the field of deep learning and distributed computing. This method first divides the input feature map of the last layer of the continuous convolutional layer into continuous sub-feature maps, and then calculates the corresponding sub-feature maps of the previous layer layer by layer according to the sub-feature maps and convolution calculation operations. Up to the first layer, refer to the sub-feature map of the first layer, segment the input feature map of the first layer, and distribute the sub-feature map after the first layer segmentation to multiple computing nodes. Finally, according to the parameters and hyperparameters of the single-link continuous convolution layer, the distributed collaborative inference without loss of precision is implemented, and after all the inference results are generated, the inference results are summarized to generate the final output feature map. Compared with the previous methods, the method of the present invention has the characteristics of greatly reducing the reasoning delay of the convolutional neural network without loss of precision.
