The data sets generated from such studies are large and require sophisticated tools for proper analysis. In this chapter we review several techniques employed in clustering data sets of this type. Clustering can often reveal broad patterns which show that certain genes or proteins are performing ...
Clustering by pattern similarity in large data sets Clustering is the process of grouping a set of objects into classes of similar objects. Although definitions of similarity vary from one clustering model t... Wang,Haixun,Wang,... 被引量: 264发表: 2014年 Grid-Clustering: An Efficient Hierarch...
Clustering large data sets might take time, particularly if you use online updates (set by default). If you have a Parallel Computing Toolbox ™ license and you set the options for parallel computing, then kmeans runs each clustering task (or replicate) in parallel. And, if Replicates>1,...
CLARA algorithm(Clustering Large Applications), which is an extension to PAM adapted for large data sets. For each of these methods, we provide: the basic idea and the key mathematical concepts the clustering algorithm and implementation in R software ...

These heuristic algorithms work well for finding spherical-shaped clusters and small to medium data sets, but they always reveal the weakness of analyzing the complex structured data such as temporal data. K-means It is one of the simplest partitional clustering algorithms and commonly used for ...
