摘　　要：针对深度神经网络在移动平台上存在准确度低、过拟合等问题,提出一种轻量级的卷积神经网络架构。将3×3的深度可分离卷积替换SqueezeNet网络模型基本模块Fire中的标准3×3卷积核,并构建SparkNet的网络结构,替换模型卷积得到网络变形结构。实验结果表明,与SqueezeNet网络结构相比,该架构可以提高网络模型的计算速度,有效降低网络模型规模并减少参数数量。For the problem that the deep neural network has low accuracy and over-fitting on the mobile platforms,a lightweight Convolutional Neural Network(CNN)architecture is proposed.The 3×3 depthwise separable convolution replaces the standard 3×3 convolution kernel in the SqueezeNet network model basic module Fire,constructs the SparkNet network structure,and replaces the model convolution to obtain the network deformation structure.Experimental results show that compared with the SqueezeNet network structure,the architecture can improve the calculation speed of the network model,effectively reduce the network model size and reduce the number of parameters.
