Multi-dimensional multi-parameter time series processing for seizure warning and prediction
First Claim
1. A computer-implemented method of analyzing a multi-dimensional system comprising the steps of:
- generating a multi-dimensional signal for each of a plurality of channels associated with the multi-dimensional system;
generating multiple dynamical profiles for each channel based on the corresponding multi-dimensional signal, where each profile reflects the dynamical characteristics of the corresponding channel in accordance with one of multiple dynamical parameters;
for a group of channels, generating a number of statistical measures, wherein each of the statistical measures reflects a correlation level between corresponding dynamical profiles, and wherein each of the corresponding dynamical profiles is associated with one of the multiple dynamical parameters;
selecting at least one dynamical parameter from amongst the multiple dynamical parameters;
generating a statistical measure for the channel group, wherein the statistical measure reflects a correlation level between corresponding dynamical profiles associated with the selected at least one dynamical parameter;
characterizing the behavior of the multi-dimensional system as a function of the statistical measure, generated for the channel group, that reflects the correlation level between corresponding dynamical profiles associated with the selected at least one dynamical parameter; and
outputting a signal indicative of the characterization of the behavior of the multi-dimensional system.

Abstract
Characterizing the behavior of a chaotic, multi-dimensional system is achieved by measuring each of a number of signals associated with the system, and generating therefrom, a spatio-temporal response based on each signal. Multiple dynamical profiles are then generated for each spatio-temporal response, where each of the multiple dynamical profiles correspond to a different one of multiple dynamical parameters. Over a period of time, a determination is made as to whether a certain level of dynamic entrainment and/or disentrainment exists between the dynamical profiles associated with a selected one or a selected combination of dynamical parameters. Seizure warnings and/or predictions are provided based on this determination.
