Choice of Measurement for Phase-Space Reconstruction: Decision Based on False Nearest Neighbors Method
نویسندگان
چکیده
False nearest neighbors (FNN) method is examinated with respect to equivariance of individual observables. The aim is to reveal the most appropriate observable for phase space reconstruction. Results calculated for benchmark systems are compared with symbolic observability degrees. The FNN method resulted in different values of embedding dimensions when calculated for various observables of the same dynamical system. The results roughly corresponded to the symbolic observability degrees; however, in some details disagreed with them.

Fractional Derivatives Applied to Phase Space Reconstructions
The concept and application of phase-space reconstructions are reviewed. Fractional derivatives are then proposed for the purpose of reconstructing dynamics from a single observed time history. A procedure is presented in which the fractional derivatives of time series data are obtained in the frequency domain. The method is applied to the Lorenz system. The ability of the method to unfold the ...

This paper compares the performance of chaos theory with Anfis model and discusses ...
متن کاملFractional Derivative Reconstruction of Forced Oscillators
Fractional derivatives are applied in the reconstruction, from a single observable, of the dynamics of a Duffing oscillator and a two-well experiment. The fractional derivatives of time series data are obtained in the frequency domain. The derivative fraction is evaluated using the average mutual information between the observable and its fractional derivative. The ability of this reconstructio...
متن کاملAnalysis of Electroencephologram Data Using Time-Delay Embeddings to Reconstruct Phase Space
In this paper, the necessary embedding dimension for electroencephologram(EEG) data is calculated. The tools used include a 1981 theorem from Floris Takens, and a subsequent extension of that theorem in 1991 given by Casdagli, Sauer and Yorke. These theorems give a method of reconstructing the phase space of the original system up to diffeomorphism using time-delays. If d is the original dimens...
متن کاملPhase space reconstruction using input-output time series data.
In this paper we suggest that an extension of a procedure recently proposed by Wayland et al. [Phys. Rev. Lett. 70, 580 (1993)] for recognizing determinism in an autonomous time series can also be used as a diagnostic for determining an appropriate embedding dimension for driven ("input-output") systems. We compare the results of this extension to the results produced by the extensions to the m...
