Classification: CPC G | IPC G

Claim 4:
5. The information processing device according to claim 1,
wherein each model of the plurality of models corresponds to a different predetermined time period value,
wherein the object is a concrete factory or a chemical plant, and
wherein the operations further comprise:
generating each model of the plurality of models based on a goodness of the time series data to a correlation model, wherein a correlation model has a correlation coefficient higher than a threshold;
selecting a model; and
generating determination data by applying the time-series data to the selected model,

wherein the selection based on maximum power corresponds to selecting a model using first time series data with more influence on the object than second time series data corresponding to the maximum power, and
wherein a significant difference between the time series data and the determination data indicates a correlation is broken with respect to a portion of the sensors related to the time series data and an anomaly has occurred in the object.
