Publication number: 20220401736Abstract: Embodiments of the disclosure are drawn to implantable stimulator with machine learning based classifier. An implantable system includes sensors which provide sensor information to an implantable unit. The implantable unit uses a classifier on the sensor information to select a stimulation procedure which is applied via a stimulation electrode. The classifier may be generated by a trained machine learning model. The classifier may be trained on an external unit which is not implanted in the subject. The classifier may be trained based on sensor information from the implanted sensors as well as symptom information.Type: ApplicationFiled: March 23, 2022Publication date: December 22, 2022Applicant: University of WashingtonInventors: Jeffrey Andrew Herron, Benjamin Isaac Ferleger, Howard Jay Chizeck, Andrew L.
