Claim 6:
7. The device according to claim 1, wherein the one or more hardware processors are configured to:
calculate the reference feature amount at a corresponding reference time for each of a plurality of reference times before the base time, based on the one or more pieces of related sensor data before the corresponding reference time and the feature amount calculation model;
estimate the reference distribution parameter in the reference period for each of the reference times, based on the reference feature amount at the corresponding reference time and the parameter estimation model; and
update the feature amount calculation model and the parameter estimation model based on: an actual measurement value of the maximum value or the minimum value of the target sensor data in the reference period corresponding to each of the reference times; and the probability distribution of the maximum value or the minimum value of the target sensor data in the reference period for each of the reference times.
