Reduction of classification error rates and monitoring system using an artificial class
View Patent ↗Systems and methods for enhancing the accuracy of classifying a measurement by providing an artificial class. Seizure prediction systems may employ a classification system including an artificial class and a user interface for signaling uncertainty in classification when a measurement is classified in the artificial class.
1. A seizure advisory system, comprising:
a user interface, the user interface comprising:
a first interface configured to provide an indication corresponding to a result of classification of data from a subject corresponding to the subject's susceptibility to a seizure;
a second interface configured to provide an indication of uncertainty when a result of classification of data from a subject is indicative of uncertainty in the classification; and
a third interface configured to receive an input from the subject.
2. The system of claim 1 , wherein the input from the subject indicates that the subject has taken a medication.
3. The system of claim 1 , wherein the input from the subject indicates that the subject has experienced a seizure.
4. The system of claim 1 , further comprising:
an implantable device configured to measure physiological signals from the subject;
wherein the user interface is provided on a device external to the subject's body.
5. The system of claim 4 , wherein the implantable device comprises a classification processor for generating the result of classification of data from the subject.
6. The system of claim 4 , wherein the external device comprises a classification processor for generating the result of classification of data from the subject.
7. The system of claim 1 , wherein the input from the subject comprises an audio input.
8. The system of claim 1 , further comprising an implantable device configured to measure physiological signals from the subject.
9. The system of claim 8 , wherein the implantable device is configured to measure brain activity signals.
10. The system of claim 8 , wherein the implantable device is configured to measure blood oxygenation.
11. The system of claim 8 , wherein the implantable device is configured to measure ECG/EKG.
12. The system of claim 1 , further comprising an implantable device configured to measure physiological signals from the subject.
13. The system of claim 12 , wherein the implantable device comprises subcutaneous electrodes.
14. The system of claim 12 , wherein the implantable device comprises intracranial electrodes.
15. The system of claim 12 , wherein the implantable device comprises a rechargeable battery.
16. A method of providing a seizure advisory to a subject, the method comprising:
providing via a first interface an indication corresponding to a result of classification of data from the subject corresponding to the subject's susceptibility to a seizure;
providing via a second interface an indication of uncertainty when a result of classification of data from a subject is indicative of uncertainty in the classification; and
receiving an input from the subject via a third interface.
17. The method of claim 16 , wherein said receiving the input from the subject comprises receiving an input from the subject indicating that the subject has taken a medication.
18. The method of claim 16 , wherein said receiving the input from the subject comprises receiving an input from the subject indicating that the subject has experienced a seizure.
19. The method of claim 16 , wherein said receiving the input from the subject comprises receiving an audio input from the subject.
20. The method of claim 16 , further comprising measuring physiological signals from the subject using an implanted device.
21. The method of claim 20 , further comprising operating a classification processor to generate the result of classification of data from the subject.
22. The method of claim 20 , wherein said measuring physiological signals from the subject comprises measuring brain activity signals.
23. The method of claim 20 , wherein said measuring physiological signals from the subject comprises measuring blood oxygenation.
24. The method of claim 20 , wherein said measuring physiological signals from the subject comprises measuring ECG/EKG.
25. The method of claim 20 , wherein said measuring physiological signals from the subject comprises measuring physiological signals using subcutaneous electrodes.
26. The method of claim 20 , wherein said measuring physiological signals from the subject comprises measuring physiological signals using intracranial electrodes.
