2009 2009 IEEE International Conference on Systems, Man and Cybernetics  
In this paper, an HPC-enabled GA-SVM (HGA-SVM) is proposed by integrating data parallelization, multithreading and heuristic techniques with the ultimate goal of robustness and low computational cost.  ...  However, the high computational cost strongly discourages the application of GA-SVM in large-scale datasets.  ...  Parallel SVM SVM training is compute-intensive because it requires quadratic programming (QP) [1] for determining the optimal separating hyperplane.  ...
