Nonlinear time series techniques

We have expertise in various techniques for characterising the complexity of signals including the use of entropy methods and novel variants of Lempel-Ziv complexity. We are developing new methods to analyse physiological data based on the method of delays and Takens embedding theory.

Our expertise

  • Attractor reconstruction methods for physiological data
  • Entropy measures
  • Variants of Lempel-Ziv complexity.
