我们仅从时间序列数据集重建Rössler方程中所有分量的分岔图,从而估计参数值变化时的吸引子。在这项研究中,我们表明,所有组件的分叉图可以重建从所有组件的时间序列数据。此外,我们还估计了重建分岔图的李雅普诺夫谱。我们预计,重建需要更短的训练数据长度时,使用的所有组件的时间序列数据集相比,一个组件。因此,在数值实验中,我们重建的分叉图使用的训练数据的长度是短于当一个分叉图重建使用训练数据的一个组件。
We reconstruct bifurcation diagrams of all components in the Rössler equations only from time-series data sets, thereby estimating the attractors when the parameter values are changed. In this study, we show that the bifurcation diagrams of all components can be reconstructed from time-series data of all components. In addition, we estimate the Lyapunov spectrum of the reconstructed bifurcation diagrams. We expect that the reconstruction requires a shorter length of training data when using time-series data sets of all components compared with one component. Accordingly, in numerical experiments, we reconstruct the bifurcation diagrams using training data whose length is shorter than when a bifurcation diagram is reconstructed using training data of one component.
