DGStream: High quality and efficiency stream clustering algorithm

作者：

Highlights：

• DGStream is a high quality and efficiency stream clustering algorithm.

• DGStream is a new online-offline grid and density-based stream clustering algorithm.

• DGStream periodically removes the sparse grids to improve the system time and space.

• DGStream adopts decaying factor to capture the dynamic changes of the stream.
