- W2032085837 abstract "The nodules and the multiple times larger non-nodules of the regions of interested(ROIs) in lung areas are achieved, that would lead to a serious imbalance on the sample data. Many scholars have proposed some algorithms to solve this problem. In this paper, in order to guarantee that there is no correlation among the extracted characteristics, the PCA method is adopted to optimize and reduce dimensions, and then the modified support vector machine(SVM) classifiers using the sequential minimal optimization(SMO) algorithm and the grid research method are proposed to improve the computing efficiency. Furthermore, the abundant lung CT images from the hospital partnership could confirm the experimental results. We compare the classification performance between the ensemble SVM(ESVM) classifier and the cost-sensitive SVM(CSVM) classifier to deal with this problem. Experimental results show the performance of the CSVM classifier based on grid search is satisfactory than the ESVM." @default.
