Scalable Varied-Density Clustering via Graph Propagation
Ninh Pham, Yingtao Zheng, Hugo Phibbs
We propose a novel perspective on varied-density clustering for high-dimensional data by framing it as a label propagation process in neighborhood graphs that adapt to local densit…

Towards Robust and Scalable Density-based Clustering via Graph Propagation
Yingtao Zheng, Hugo Phibbs, Ninh Pham
We present \textit{CluProp}, a novel framework that reimagines varied-density clustering in high-dimensional spaces as a label propagation process over neighborhood graphs. Our app…

Scalable Density-based Clustering with Random Projections
Haochuan Xu, Ninh Pham
We present sDBSCAN, a scalable density-based clustering algorithm in high dimensions with cosine distance. Utilizing the neighborhood-preserving property of random projections, sDB…
