Abstract:
1. A method of displaying a graphical representation of a patient's condition as measured by n parameters, where n>3, comprising mapping data points represented by said n parameters from an n-dimensional measurement space into an m-dimensional visualization space, where m<n, using a dimensionality reduction mapping, and displaying the visualization space and the data points mapped into it, and wherein the displaying is adapted to the display of dynamically changing values of said parameters by means of the mapping being carried out by a trained artificial neural network, wherein said mapping maps each data point on receipt onto a novelty index constituting a one dimensional visualization space and the value of said novelty index is displayed against time, and wherein the novelty index of each point is based on its distance in the n-dimensional measurement space from a predefined set of points representing a normal condition for the patient.
