| Research Abstract |
Various approaches for learning probabilistic models from given data and background knowledge have been studied in the past, however, studies on the probabilistic model learning for rare/special conditions have been very limited. In this study, we developed an efficient and accurate approach to learn probabilistic simulation models for the rare/special conditions by using a given data set and its associated background knowledge. Moreover, we demonstrated a novel framework for the probabilistic estimation and prediction of rare/special events and scenarios through its applications to a rare and large scale natural disaster.
