| 中文摘要 |
| 混沌神经网络已经被证明是解决组合优化问题的有效工具. 针对混沌神经网络的单调的激励函数, 通过引入Shannon小波和Sigmoid 函数加和组成的非单调激励函数, 提出了一种新型的暂态混沌神经元模型. 给出了该混沌神经元的倒分岔图和最大Lyapunov指数时间演化图, 分析了其动力学特性. 基于该模型, 构造了一种暂态混沌神经网络, 并将其应用于函数优化和组合优化问题. 通过经典的10城市TSP验证了该暂态混沌神经网络的有效性. |
| 英文摘要 |
| Chaotic neural network has been proved to be a valid tool for solving combinational optimization problems. Referring to the monotonous activation function of chaotic neural network, we present a novel transient chaotic-neuron model by introducing the Shannon wavelet and the Sigmoid activation function to compose the non-monotonous activation function. The reversed bifurcation and the maximum Lyapunov exponent of the chaotic neuron are given and the dynamic system is analyzed. Based on the neuron model, a novel transient chaotic-neural network is made and applied to functionoptimization and combinational optimization problems. The simulation results of TSP in 10 cities indicate the validity of this novel transient chaotic-neural network. |
