Data Mining of Geographical Accessibility for Tourism in Regional Area

Based on an entropy maximization principle both the spatial interaction model and the discrete choice model are discussed first to clarify the meaning of the accessibility and the utility function. We next introduce a mixture of expert that is one kind of probabilistic neural network and define the preference function in the MoE. The presented model can be consider a merged one of the spatial interaction model and the discrete choice model, so the relations among the utility, preference and accessibility can be shown in a unified way. Goal is to show availability of application of those properties to data mining of geographical accessibility for tourism in regional area.
