  • Fast, continuous psychometric estimation system utilizing machine learning and associated method of use
    Patent number: 11037677
    Abstract: A method and system for of computerized psychometric testing of sensory information that includes selecting stimulus parameters for a first stimulus to be applied with a stimulus inducer, applying a first stimulus on a subject with the stimulus inducer upon command of a processor, calculating a posterior probability function and an acquisition function at least based on the subject's response to the first stimulus with the processor, determining stimulus parameters for a second stimulus based on the calculated acquisition function with the processor, stimulating the subject with the second stimulus with the stimulus inducer upon command of the processor, and determining a detection threshold function by calculating the posterior probability function at least based on the subject's response to the second stimulus with the processor.
