摘要: 激活函数是人工神经网络的重要组成部分,对提高人工神经网络的准确性具有重要影响。为了研究使用混合激活函数的卷积神经网络在图像分类任务中的识别精度和收敛速度表现,本工作以LeNet5卷积神经网络为基本结构,构造了一个使用SinusoidSinusoidRamp(SSR)混合激活函数的卷积神经网络,以及4个使用单一激活函数(Sinusoid、Ramp、Sigmoid、Tanh)的卷积神经网络在CIFAR10数据集上进行了图像分类实验,并在MNIST数据集上将本工作新模型同其他分类算法的效果进行了对比。结果表明,使用SSR混合激活函数的卷积神经网络具有更快的收敛速度和更高的识别精度。

Abstract: The activation function is an important part of artificial neural networks and has an important impact on improving the accuracy of artificial neural networks. In order to study the effect of using hybrid activation function convolutional neural networks to improve image classification accuracy and the convergence speed of models, This paper uses the Lenet5 convolutional neural network as the basic structure, and constructs a convolutional neural network using SSR (S: Sine function, R: Ramp function) mixed activation function, and four single activation function (Sine, Ramp, Sigmoid, Tanh) convolutional neural networks perform image classification experiments on the CIFAR10 dataset. And compare our new model with other classification algorithms on the MNIST dataset. The results show that the convolutional neural network using the SSR hybrid activation functions has faster convergence speed and higher recognition accuracy.
