Parallel Spectral Clustering


Spectral clustering algorithm has been shown to be more e ective in nding clusters than most traditional algorithms. However, spectral clustering su ers from a scalability problem in both memory use and computational time when a dataset size is large. To perform clustering on large datasets, we propose to parallelize both memory use and computation on distributed computers. Through an empirical study on a large document dataset of 193,844 data instances and a large photo dataset of 637,137, we demonstrate that our parallel algorithm can effectively alleviate the scalability problem.
