Regional co-location patterns represent subsets of object types that are located together in space (i.e. region). Discovering regional spatial co-location patterns is an important problem with many application domains. There are different methods in this field but they encounter a big problem: finding a unique optimum neighborhood radius or finding an optimum k value for nearest neighbor features. Here, the authors developed a method that considers a neighborhood interval using fuzzy definition of neighborhood. It is easier to apply the proposed method for different applications.
