Extracting Qualitative Dynamics from Experimental Data

  title={Extracting Qualitative Dynamics from Experimental Data},
  author={David S. Broomhead and Gregory R. King},
In this paper we consider the notion of qualitutiue informationt and how it may be extracted from experimental time series. That this type of information might be recovered from a time series was first suggested by Packard et al. [l]. These authors suggested that a phase portrait, equivalent in some sense to that of the underlying dynamical system, could be reconstructed from time derivatives formed from the data. Another method of phase portrait reconstruction was suggested independently by… CONTINUE READING
