| 摘 要： | 用脊波函数作为单隐层神经网络的激活函数,针对此种网络提出了一种两阶段的参数估计优化算法:用进化算法来优化网络中的尺度、方向和位置参数,用最小二乘法来估计网络中的线性权重。把此种模型和优化方法用于预测著名的Mackey-Glass混沌时间序列。比较结果表明了提出方法的有效性。

| Abstract: | This paper uses ridgelet function as the activation function of a single hidden layer neural network.A two-phase optimization algorithm is proposed to estimate the ridgelet network.First,the evolutionary algorithm is used to optimize the sacle,direction and location of the network;second,the least-squares method is used to estimate the linear weights of the network.The ridgelet netowrk model estimated by the proposed optimazation algorithm is used to predict the famous Mackey-Glass time series.Comparing res... |
