The real-time data stream clustering and the detection of clustering boundary is an interesting research work. This paper proposes a clustering algorithm named DDBound with boundary detection ability for grid clustering based on distance and density. DDBound firstly calculates the densities of all grids, and divides them into high-density grids and low-density grids. From all grids, the algorithm...
An important class of data mining problems is clustering. The traditional clustering algorithm is a kind of hard partition and it parts strictly each object into some cluster. But the real object is not always having distinct attributes, so fuzzy theory is introduced to deal with it. In this paper an improved algorithm is introduced based on the research of fuzzy theory and other clustering algorithms...
