Outline of Final Research Achievements

In this study, I have developed a novel and general spatial analysis method for relatively small space such as architectures and streets. This analysis method can statistically explain and predict the place where human’s unconscious activities might occur in the space which essentially has vague boundary. In addition, this method can automatically decide the shape of the area in which such activities might occuer based on the concept of semi-supervised clustering. I applied this method to the artificial data and the actual data of pedestrians rendezvousing in Umeda Underground Mall and got good results.
