Customer segmentation application of PSO parallel cluster;

A parallel cluster algorithm for self-adaptive particle swarm optimization was proposed to deal with this problem.

Small targets detection based on hierarchical clustering;

A new hierarchical clustering algorithm based on tree edit distance;

Combined unsupervised image segmentation using watershed and hierarchical clustering with MRF;

Based on the multi-dimensional approximate periodic pattern, we present an algorithm to mine multi-dimensional temporal approximate periodicity with the algorithm of hierarchical cluster, then applies to the stock data.

An equivalence relation ≡HCov is proposed based on the Data Cube s semantics and the dimension s hierarchy of its pattern, and then on the basis of the equivalence relation, proceeds the data cube to hierarchical cluster.

The result, normally overpredicted by traditional Environment Envelope Model, is improved by using hierarchical cluster arith- metic that can reduce the influence caused by outliers.

On the basis of researching and concluding the development procedure of volume rendering and its key technology,combined with multi-core cluster,a parallel ray casting volume rendering algorithm based on hierarchical parallel programming model has been proposed in this paper.
