E. Bagarinao et al., Reconstructing bifurcation diagrams from noisy time series using nonlinearautoregressive models, PHYS REV E, 60(1), 1999, pp. 1073-1076
We introduce a formalism for the reconstruction of bifurcation diagrams fro
m noisy time series. The method consists in finding a parametrized predicto
r function whose bifurcation structure is similar to that of the given syst
em. The reconstruction algorithm is composed of two stages: model selection
and bifurcation parameter identification. In the first stage, an appropria
te model that best represents all the given time series is selected. A nonl
inear autoregressive model with polynomial terms is employed in this study.
The identification of the bifurcation parameters from among the many model
parameters is done in the second stage. The algorithm works well even for
a limited number of time series. [S1063-651X(99)12607-2].
