Abstract
A characteristic value estimation device has a sensor data input unit to input sensor data detected by one or more sensors, a model input unit to input a first calculation model, a model learning unit to perform learning on a second calculation model, a model switch to select any one of the first calculation model and the second calculation model, a predictive value calculation unit to calculate an error of the calculation model, a probability distribution correction unit to correct the probability distribution of the uncertain parameter, a virtual sensor value estimation unit to estimate sensor data of a virtual sensor arranged virtually, a characteristic value distribution estimation unit to estimate a detailed distribution of the characteristic value, the sensor data of the virtual sensor, and the sensor data of the sensor, and a reliability calculation unit to calculate a reliability of the precise characteristic value distribution.
