Abstract
A predictive detection apparatus includes a preprocessing section that acquires a chronological feature amount indicating an operational status of an apparatus to be cooled which includes a heat source and a cooling section that cools the heat source with a cooling medium, and a model creation section that generates a training data set in reference to the chronological feature amount acquired by the preprocessing section and a label indicating whether a cooling capability provided by the cooling section is normal or abnormal, and that uses the training data set to create a predictive detection model.
