Abstract: A determination apparatus includes circuitry to receive operation information corresponding to an action being performed by a machine to be diagnosed and a detection signal of a physical quantity that changes according to the action of the machine; take out, from the detection signal, an operation detection signal indicating that the machine is operating, based on the operation information; extract feature information of the operation detection signal; select, from the feature information, particular feature information to be compared with a plurality of reference feature information; and determine a machining section of the machine in the feature information, based on the plurality of reference feature information and the particular feature information.

Abstract: An information processing apparatus includes a detection result acquisition unit configured to acquire a detection result of a physical quantity that changes as a movable body moves while being in contact with a subject; an image data acquisition unit configured to acquire image data of the subject; and a display control unit configured to control a display to display likelihood information indicating a likelihood of abnormality of the subject and the image data in association with each other. The likelihood is determined based on the detection result.
