| Abstract(in English) | Some real systems compose networks where each element interacts with each other. We can obtain their behavior as time series data, and can use them for understanding mechanisms of systems and predicting future behavior. For example, in economic systems, each company corresponds to a node of a network and interacts with each company. Thus, stock markets show us complex movements. In the case of predicting such movements, it is possible that the difficulty of prediction and the optimum model of prediction are different according to properties of each node, such as large company or medium company. In this study, we prepared some coupled chaos systems with the WS model, which generates the small-world network, as numerical models to model real systems. Then, we predicted time series generated by coupled chaos systems by nonlinear prediction method. In addition, we examined the correlations between prediction accuracies of each node and centralities of each node:degree centrality, betweenness centrality and closeness centrality, and then we discuss the predictability of complex real system like economic systems. |
