Abstract: A learning model is trained to output output data indicating an inference result regarding an ultrasound image that is a medical image, based on input data representing the ultrasound image. An inference parameter change unit changes an inference parameter, which is a parameter that is an adjustment target in training processing of the learning model and that affects the output data, in response to an instruction from a user. An inference processing unit outputs an inference result regarding a target ultrasound image, which is an inference processing target, based on output data in a case in which the target ultrasound image is input to the learning model having the changed inference parameter.
