Abstract | In this paper, the problem of finding the number of optimal cluster partitions in fuzzy domain has been countered. The fact motivated us to develop an algorithm on differential evolution for automatic cluster detection from the unknown data set. Here, assignments of points to different clusters are done based on a Xie-Beni index where the euclidean distance takes into consideration. The cluster centers are encoded in the vectors, and the Xie-Beni index is used as a measure of the validity of the corresponding partition. The effectiveness of the proposed technique is demonstrated for two synthetic and two real life data sets. Superiority of the new method is demonstrated by comparing it with the variable length genetic algorithm based fuzzy clustering and well known Fuzzy C-Means algorithm. |

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.
