| Abstract | For classification problem clustering method divides the dataset into many clusters based on correlation attribute of all elements of the dataset. How to classify data within the same clustering number as close as possible and data in different clusters as depart as possible is the key of clustering method. Clustering support vector machines (ClusterSVM) partition the training data into disjoint clusters first, then train an initial support vectors using representatives of these clusters. These initial support vectors which give us a global picture of the solution can approximately identify the support vectors and non-support vectors. The training process is accelerated by replacing non-support vectors with few data. The initial SVM of cluster is the key of training ClusterSVM. This paper proposed a reduced kernel matrix to generate a nonlinear separating surface which depends on a small randomly selected portion of the dataset, and used this kernel to train the initial SVM of clusters. Computational results indicate computational times as well as the number of training data are much smaller for the improved method than that of a conventional ClusterSVM. |

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.
