GSnet: combine Ghostnet and Shufflenetv2 to get better performance

In computer vision technology based on deep learning, the backbone network is very important, and its performance can usually affect vision-related tasks such as target detection and target segmentation. This article proposes a Ghostnet improvement strategy combined with Shufflenetv2 named GSnet. This paper uses Shufflenetv2's concatenate and shuffle operations to further improve Ghostnet. And the attention module in Ghostnet has been improved and optimized. This paper uses long-distance non-local features to further improve SA attention and embed it in Ghostnet. Experiments are carried out with the data set of cifar100, and after experimental verification, this method reduces the amount of parameters and calculations on the basis of the original method and improves the accuracy of TOP1 by 1.26%.
