an efficient approach for clustering high dimensional data
... High-dimensional data arise naturally in many domains. It presented a great challenge for traditional data mining techniques, both in terms of effectiveness and efficiency. Clustering becomes difficult due to the increasing sparsity of such data, as well as the increasing difficulty in distinguishin ...

Generalized Cluster Aggregation
... Bayesian method [Wang et al., 2009]. Most of the traditional approaches treat each input clustering equally. Recently, some researchers proposed to weigh different clusterings differently when performing cluster aggregation to further improve the diversity and reduce the redundancy in combining the ...

A Fast Clustering Based Feature Subset Selection Using Affinity
... Abstract: Clustering which tries to group a set of points into clusters such that points in the same cluster are more similar to each other than points in different clusters, under a particular similarity metric. In the generative clustering model, a parametric form of data generation is assumed, an ...
