Abstract
This technology provides the ability to determine abnormalities or signs of abnormalities in a subject with high accuracy, without requiring specialized skills. [Solution] The abnormality detection device 30 of this embodiment generates first data D1 having 24 feature quantities from water usage data for a specific period collected from a water meter device 10 installed in the subject's residence H. Then, the first data D1 is converted into second data D2 having 2 feature quantities by a trained model 20 trained by an autoencoder and used to determine whether the subject has an abnormality or a precursor thereof. In this way, the number of dimensions of the data used for determination is reduced, making determination easier, and it becomes possible to determine whether the subject has an abnormality or a precursor thereof with high accuracy based on multi-dimensional data without requiring expertise.
