摘要:

本研究分析了复杂网络下线性平均一致性算法的加速问题。我们提出一种数据驱动方法,借助深度学习技术调整时序(即时变)网络的权重。在给定有限时间窗下,该方法首先将线性平均一致性协议展开,得到一个前馈信号流图,并将其视作神经网络。随后使用标准深度学习技术训练所得神经网络的边权重,以最小化给定有限时间窗内的一致性误差。通过该训练过程,我们得到一组优化的时变权重,可实现复杂网络下更快的一致性。我们还证明该方法可拓展至无限时间窗问题。数值实验表明,与基线策略相比,我们的方法能实现显著更低的一致性误差。

英文摘要:

In this study, we analyzed the problem of accelerating the linear average consensus algorithm for complex networks. We propose a data-driven approach to tuning the weights of temporal (i.e., time-varying) networks using deep learning techniques. Given a finite-time window, the proposed approach first unfolds the linear average consensus protocol to obtain a feedforward signal-flow graph, which is regarded as a neural network. The edge weights of the obtained neural network are then trained using standard deep learning techniques to minimize consensus error over a given finite-time window. Through this training process, we obtain a set of optimized time-varying weights, which yield faster consensus for a complex network. We also demonstrate that the proposed approach can be extended for infinite-time window problems. Numerical experiments revealed that our approach can achieve a significantly smaller consensus error compared to baseline strategies.
