1. A density grid-based clustering algorithm for uncertain data streams
... Abstract: This paper proposes a grid-based clustering algorithm Clu-US which is competent to find clusters of nonconvex shapes on uncertain data stream. Clu-US maps the uncertain data tuples to the grid space which could store and update the summary information of stream. The uncertainty of data is ...
