Abstract
A method of extracting features and classifying a neurological state of a subject is provided. The method includes recording brain electrical activity, organizing the recorded data set into digital documents, computing a diffusion geometry on the data set comprising at least a plurality of diffusion coordinates, and classifying the data set into a neurological state based on the metrics provided by the diffusion coordinates.
Claims34
A method of determining a neurological state of subject comprising the steps of:
- acquiring electrical signals from the brain using at least one electrode channel;
- extracting features from the acquired signals;
- and
- classifying the extracted features into one or more diagnostic categories;
- wherein the steps of extracting features and classifying extracted features is performed using diffusion geometric analysis.
A method of classifying a neurological state of subject using diffusion geometry of a data set.
An apparatus for signal processing, comprising:
- a signal receiver unit or a headset;
- a handheld base unit, wherein
- a processor is configured to utilize one or more operating instructions stored in a memory to perform denoising of the received signal, extract features, and classify the signal using diffusion geometric analysis;
- a display unit, wherein a result from the processor is displayed.
