PROBLEM TO BE SOLVED: To provide a technology that improves accuracy in a motor function estimated on the basis of sensor data of a prolonged period.SOLUTION: A motor function estimation information generating device acquires a sensor value and a motor ability value of a user, determines a feature of the sensor value and a time section within a predetermined period, calculates a feature vector corresponding to a feature amount of the feature in the time section by using the sensor value, acquires a first weight vector by using the feature vector and the motor ability value, calculates a gradient vector relating to the feature vector by using the first weight vector and the motor ability value, determines a new time section within the predetermined period and a new feature amount based on the new time section, calculates a feature candidate vector corresponding to a feature amount of the new feature in the new time section by using the sensor value, determines the feature candidate vector that satisfies a predetermined condition based on the gradient vector on the basis of a difference between the feature candidate vector and the feature vector, and corrects the first weight vector to a second weight vector by using the feature candidate vector that satisfies the predetermined condition.SELECTED DRAWING: Figure 1
