Abstract(in English) | This paper proposes a novel method for estimating the physical quantity at every location (physical quan- tity field) from sensor data obtained at several locations of the environment. We use the low precision sensors that are not calibrated and the high precision sensors that are fewer than those sensors. When the physical quantity field is discontinuous, the estimation accuracy decreases with the existing method. In this paper, A probabilistic generation model is constructed and the posterior probability of the field is obtained by variational Bayes in consideration of the systematic error of the low precision sensors and the discontinuity of the physical quantity field. |
