This paper proposes a new recurrent neural network for solving nonlinear projection equations. The proposed neural network has a one-layer structure and is suitable for parallel implementation. The proposed neural network is guaranteed to be globally convergent to an exact solution under mild conditions of the underlying nonlinear mapping. Compared with existing neural networks for nonlinear optimization, the asymptotical stability and exponential stability of the the proposed network are obtained without the smooth condition of the nonlinear mapping. The proposed neural network can be used to find the equilibrium point of both the projection neural network and Hopfield-type neural network. Therefore, the proposed neural network is a good solver for a wider class of optimization and related problems. Illustrative examples further show that the proposed neural network can obtain a more accurate solution with a faster convergence rate than existing relevant methods.
本文提出了一种用于求解非线性投影方程的新型递归神经网络。所提出的神经网络具有单层结构,适用于并行实现。在所提出的非线性映射的温和条件下,所提出的神经网络被保证全局收敛到精确解。与现有的用于非线性优化的神经网络相比,所提出的网络在没有非线性映射的光滑条件下获得了渐近稳定性和指数稳定性。所提出的神经网络可用于找到投影神经网络和霍普菲尔德型神经网络的平衡点。因此,所提出的神经网络是一类更广泛的优化及相关问题的良好求解器。示例进一步表明,所提出的神经网络比现有相关方法能以更快的收敛速度获得更精确的解。
