Abstract(in English) | New network services are expected to emerge using real spatial information in remote areas. For the advancement of services, it is important to understand real space from real spatial information, and for this purpose, object identification technology using machine learning is being introduced. In this paper, we have tried to represent real space as a field of probabilistic superposition of objects, instead of directly identifying real space information using machine learning techniques. We obtain neighboring information based on the positional relationships of objects in real space from a dataset used by the machine learning. Then, we propose a method of estimating objects by adding empirical knowledge information of real space to the object identification results. Our results show that predictions are changed by adapted empirical knowledge information and the estimation accuracy is improved when the confidence by the machine learning is not high. |
