Title: ESTIMATION DEVICE, ESTIMATION METHOD, AND PROGRAM
Abstract:
An estimation device (10) equipped with: a data acquisition unit (11) that acquires measurement data for the electric current consumption or the electric power consumption of all of multiple electric devices being monitored; an estimation unit (12) that executes a first estimation process in which the electric current consumption or the electric power consumption of each of the multiple electric devices is estimated on the basis of a first training data group having multiple items of training data wherein, for each electric device, the electric current consumption value or the electric power consumption value is associated with a characteristic amount included in measurement data during operation with that electric current consumption value or electric power consumption value, and a second estimation process in which the electric current consumption or the electric power consumption of each of the multiple electric devices is estimated on the basis of a second training data group having fewer items of training data than the first training data group; and a selection unit (13) that selects an estimation process from multiple estimation processes, including the first estimation process and the second estimation process. The estimation unit (12) executes the estimation process selected by the selection unit (13).
