Lifetime distributions for adjacency relationships in a Vicsek model
Takuma Narizuka, Yoshihiro Yamazaki
We investigate the statistical properties of adjacency relationships in a two-dimensional Vicsek model. We define adjacent edges for all particles at every time step by (a) Delauna…
Universal topological representation of geometric patterns
Shousuke Ohmori, Yoshihiro Yamazaki, Tomoyuki Yamamoto +1
We discuss here geometric structures of condensed matters by means of a fundamental topological method. Any geometric pattern can be universally represented by a decomposition spac…
Clustering algorithm for formations in football games
Takuma Narizuka, Yoshihiro Yamazaki
This paper develops a clustering algorithm for formations in team sports, with a focus on football games. Our method first clusters formations into several average formations: `442…
Characterization of the formation structure in team sports
Takuma Narizuka, Yoshihiro Yamazaki
We propose a method to identify the formation structure in team sports based on Delaunay triangulation. The adjacency matrix obtained from the Delaunay triangulation for each playe…
