Abstract
A detection device generates plural attractors based on brainwave data. Subsequently, the detection device calculates a Betti number by subjecting the attractors to persistent homology transform. The detection device determines an onset of encephalopathy based on a first order component of a Betti sequence calculated based on the Betti number.
Claims7
A non-transitory computer-readable recording medium having stored therein an encephalopathy determination program that causes a computer to execute a process comprising:
- acquiring brainwave data of a patient;
- generating a plurality of attractors based on the brainwave data;
- calculating a Betti number based on time periods of existence of first order holes occurring by subjecting the plurality of attractors to persistent homology transform;
- determining that an onset of encephalopathy of the patient is developed when an area of a first order component is equal to or larger than a threshold in a Betti sequence indicated by a graph of the Betti number against time;
- and
- when encephalopathy is detected based on the result of the determining, notifying that the encephalopathy is detected to the medical staff, and displaying the determined result of the onset of the encephalopathy.
An encephalopathy determination method comprising:
- acquiring brainwave data of a patient;
- generating a plurality of attractors based on the brainwave data acquired, using a processor;
- calculating a Betti number based on time periods of existence of first order holes occurring by subjecting the plurality of attractors to persistent homology transform, using the processor;
- determining that an onset of encephalopathy of the patient is developed when an area of a first order component is equal to or larger than a threshold in a Betti sequence indicated by a graph of the Betti number against time, using the processor;
- and
- when the encephalopathy is detected based on the result of the determining, notifying that the encephalopathy is detected to the medical staff, and displaying the determined result of the onset of the encephalopathy.
An information processing apparatus comprising:
- a processor configured to:
- acquire brainwave data of a patient;
- generate a plurality of pseudo-attractors based on the brainwave data;
- calculate a Betti number based on time periods of existence of first order holes occurring by subjecting the plurality of attractors to persistent homology transform;
- determine that an onset of encephalopathy of the patient is developed when an area of a first order component is equal to or larger than a threshold in a Betti sequence indicated by a graph of the Betti number against time;
- and
- notify that the encephalopathy is detected to a medical staff, and display the determined result of the onset of the encephalopathy when the encephalopathy is detected based on the determined result.
