| Abstract(in English) | This paper proposes a new approach to cluster and to summarize trajectories of a large number of moving objects. Former proposals on moving object clustering often use distances between trajectories for their clustering. However, since the distribution of movement patterns are not fully considered, the overall feature of the movements is not necessarily represented. In the proposed method, movement patterns are modeled according to the Markov chain model, and an information theory-based clustering is applied. The clustering method is an extension of the Information Bottleneck method and aims to find clusters that has minimum information loss (that means the increase of vagueness will be large). The proposed method relates the problem of summarization of trajectories and the increase of vagueness. This paper describe the basic idea of the proposed method. |
