摘要

•The proposed method extends grid-based DBSCAN scalable to higher-dimensional dataset.•Cluster forest is devised to alleviate redundancies in the merging step.•HyperGrid Bitmap is used to index non-empty grids for efficient neighbor grid queries.•Experiments show performance superiority of proposed method on real/synthetic data.
