Switching Regression Considering Direction-dependent Uncertainty and Its Application to Solar Electric Power Analysis
Shunsuke Iwata, Katsuhiro Honda, Akira Notsu
Switching regression is a data mining tool for revealing intrinsic non-linear dependencies among exploratory and objective variables, and Fuzzy c-Regression Models (FCRM) is an FCM-type switching regression algorithm. In this paper, FCRM is applied to a residential solar electric power analysis. Because meteorological observation of actual sunshine duration is often underestimated from the actual quantity of solar radiation, we often fail to reveal intrinsic relation among solar electric power and sunshine duration. In this paper, FCRM is modied for handling direction-dependent uncertain observations in an element-wise manner and its applicability is demonstrated with several experimental results.
