Abstract: For deep fusion in the middle layer branches of deep neural networks, it is a challenge for recent deep neural network research to generate a basic network that can share useful information, thereby optimizing information flow and improving the performance of deep neural networks. In this paper, the deep neural network based on attention convolution module is proposed. The proposed module is mainly divided into two parts：the trunk branch and the soft branch. On the trunk branch, it consists of two sets of residual modules, making the module suitable for other deep neural networks. On the soft branch, the given intermediate feature map is taken along two dimensions （space and channel） to obtain the attention feature map, and the input intermediate feature map is adjusted to strengthen useful information to suppress useless information. The proposed convolution residual module can solve the problem of inconsistent input and output size, strengthen the key information of the image and effectively promote the information flow of the network. Experiments on the cifar-10, cifar-100, ck+, AVEC2017 data sets show that the proposed method applied to the resnet-50 network has a higher recognition accuracy（0.9%~1.2%） than the method proposed by Hu when the training time difference is less than 0.3%.
