| Abstract | Feature extraction is an important task before weapon system cost forecasting modeling, which affects the forecasting performance of the model. In this paper, feature extraction in the weapon system cost forecasting was studied. In regard to the mechanism of feature extraction and the good performance of support vector machine (SVM), principal components analysis (PCA) and kernel principal components analysis (KPCA) were compared and the SVM-based cost forecasting model was adopted. A cost forecasting modeling framework based on KPCA&SVM was established. At the same time, three cases of cost forecasting, SVM, PCA+SVM and KPCA + SVM, were compared. In addition, considering the consistency of feature extraction and the establishment of cost forecasting model, a joint optimization method based on particle swarm optimization (PSO) was adopted, which can simultaneously achieve feature extraction and the optimization of cost forecasting model. And the characteristics and advantages of the kernel method were analyzed. The calculation results show the good application effect and prospect of feature extraction based on KPCA in the weapon system cost forecasting. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
