Publication number: 20260034362Abstract: User-specific neurostimulation settings are efficiently determined and optimized based on an optimized set of population-based neurostimulation settings. The population data are clustered and a set of test settings for a new user are selected as settings that efficiently discriminate between the clusters. User preference of the test settings are used to map the user to a particular cluster of settings, which can be used to determine user-specific neurostimulation settings. The user-based settings can be iteratively updated and/or optimized using information from the population data, such as by using average preference score surfaces in the population data to identify and/or filter new test settings for the user.Type: ApplicationFiled: June 4, 2025Publication date: February 5, 2026Inventors: Theoden I.

Publication number: 20240293677Abstract: A medical device is controlled based in part on a Bayesian preference learning-based optimization of the control parameters of the device. The Bayesian preference learning-based optimization is implemented to identify personalized optimal control parameters based on user preference for control parameter settings. The Bayesian preference learning-based optimization provides automatic tuning of the control parameters of the medical device based on feedback data, such as user response data, to achieve a user-specific therapy or effect.Type: ApplicationFiled: July 15, 2022Publication date: September 5, 2024Applicant: Regents of the University of MinnesotaInventors: Theoden I.
