Abstract: A control device includes a trained model for receiving a feature amount calculated from information collected from the control target to output a score, and a threshold value for determining the score An information processing device displays a feature amount related to the trained model and a score calculated from the feature amount, receives setting of a threshold value for any of the feature amount and the score, calculates a threshold value for the score from the threshold value set for the feature amount, and outputs, as a threshold value to be applied to the trained model, any of the threshold value set for the score and the threshold value for the score calculated from the threshold value set for the feature amount.

Abstract: Provided is an information processing apparatus for generating a predictive model. The predictive model is configured to calculate, at a prediction start point, a value at a prediction point in the future by a predetermined time margin from the prediction start point. The information processing apparatus includes a reception unit configured to receive a setting of the prediction point, a setting of an explanatory variable section corresponding to a range including the prediction start point and a period before the prediction start point, and selection of one or more positions from among a plurality of position candidates in the explanatory variable section, and a calculation unit configured to calculate prediction accuracy of the value at the prediction point using one or more actual values at the selected one or more positions based on time series data of the actual value corresponding to the value calculated by the predictive model.

Abstract: According to the present invention, an axial force of a screw which is generated by screw driving is estimated. A control part applies a predetermined torque generated by a rotation axis servomotor to a screw in a rotation direction where a screw is driven, and thereafter releases the torque. The control part then estimates an axial force of the driven screw based on fluctuation of a rotation position of the rotation axis servomotor which occurs due to the release of the torque.
