<p>In one embodiment, a calculator calculates power consumed by devices and a feature at a time interval on a current and/or a voltage of a power supplier, a generating unit calculates a difference between the power consumption at the starting time and each power consumption and a difference between the feature at the starting time and each feature, in a first period from the starting time, for each device, creates, for each combination of the devices, a set of learning data including power consumption differences of devices therein and a sum of feature differences of the devices therein, generates a model to estimate, as a function of a first variable indicating the sum of feature differences, second variables indicating power consumption differences of each device, a estimating unit estimates power consumption of each device based on the model and the feature, the feature being given to the first variable.</p> |
