Abstract: An information processing device includes a sensor that measures predetermined data, a model storage unit that stores a model obtained by modeling time series data measured in the past, an information amount computation unit that computes an information amount obtained from measurement based on the difference of an information amount when measurement by the sensor is not performed which is decided based on a prior distribution of state variables of the model and an information amount when measurement by the sensor is performed which is decided based on a posterior distribution of the state variables of the model, and a measurement control unit that controls the sensor based on the information amount obtained from the measurement.
