Nov 14, 2011 · tral clustering algorithms using empty region graphs and a diffusion- based local scaling approach. We learned that empty region graphs such ...
A subset of empty region graphs - the β-skeleton - and non-linear diffusion are employed to define a locally-adapted affinity matrix, which provides higher ...
Aug 16, 2012 · In this paper, we propose the use of the one-parameter β-skeleton empty region graph to construct locally-scaled affinity matrices that improve ...

Bibliographic details on Locally-scaled spectral clustering using empty region graphs.
The problem of clustering can now be reformulated using the similarity graph: we want to find a partition of the graph such that the edges between different ...

The first step is to construct a similarity graph for all the data points. • The data points are embedded in a space, in which the clusters are more “obvious,” ...
