Title: Complexity Science for Physiological Recordings: A Way to Assess the State of Body and Mind

Abstract:

Complex physical and biological systems are characterised by a large number of degrees of freedom and inherent adaptability. When it comes to living organisms, the complexity loss theory states that organisms under constraints (ageing, illness) exhibit loss of complexity of their physiological responses, (cf. loss of degrees of freedom for physical systems). This framework has created a paradigm shift in the way we approach (structural) health of dynamic systems, but critically depends on the estimation of entropy. Probability and entropy are notoriously difficult to estimate from real world noisy and no stationary data, and we need to resort to practical entropy estimators suitable for this purpose. This talk will cover some new developments in complexity science, based on nonparametric entropy estimators, such as Multivariate Multiscale Sample Entropy (MMSE), and will illuminate how this can be used to assess the state of body and mind of humans (ageing, fatigue, stress), or degree of their recovery from illness. A novel algorithm will be presented which considers long term correlations as a signature of complexity (as opposed to the classic uncertainty) and its benefits will be illustrated over several examples in a system identification setting. The applications of complexity science presented in this talk include examples ranging from visual perception through to cardiovascular health.
