A New Shared Nearest Neighbor Clustering Algorithm and its Applications
TL;DR: This paper offers definitions of density and similarity that work well for high dimensional data (actually, for data of any dimensionality), and uses a similarity measure that is based on the number of neighbors that two points share, and defines the density of a point as the sum of the similarities of a points’s nearest neighbors.
Clustering Based on Association Rule Hypergraphs
TL;DR: Compared to the existing clustering algorithmAutoclass, this algorithm produced comparable quality clusters in the congressional voting data and is linearly scalable with respect to the number of transactions.
