Abstract
We propose a method to reproduce distance matrices and original time series
from recurrence plots. The procedure is to (i) convert a recurrence plot
to a weighted graph and (ii) calculate a distance between each pair
of nodes on this weighted graph.
We demonstrate this method by reproducing the topological shape of
original time series.
We also propose two applications.
The first application is to obtain the maximal Lyapunov exponent
from a recurrence plot without reproducing the shapes
of original time series.
The second application is to reconstruct a common deterministic driving
force from observations of forced systems.
Thus, the method opens new fields in data analysis.
