An improved time-variant logistic-CML model

An improved time-variant coupled map lattice (CML) model is proposed. Initially, a real signal was adopted. Then radial basis function(RBF) is used to indicate the time-variant map coefficient. Finally, by using different CML models, different predicted signals were obtained. The correlation coefficients between the real signal and the predicted signal indicated the fitting capacity to real system. Simulation results show that the proposed method can effectively simulate the development process of a spatiotemporal nonlinear system.
