| Abstract | Irrelevant or redundant features may have negative effects on classification algorithms. The designer of a classification algorithm typically require a few very significant features characterising the class membership of the patterns. The discriminatory information is encoded in a very complex manner and features which are the most important for pattern classification may not be apparent. One way to address this problem is the use of feature weighting procedure as a data preprocessing step. In this paper we propose a two-step algorithm as an extension of the learning vector quantization algorithm (LVQ). This approach is based on weighting features depending on their contribution to discrimination. Adapting weighting coefficients and codewords is done simultaneously by using a new global learning algorithm named /spl omega/LVQ2. Experiments are undertaken on a synthetic problem and on real problems in speech and speaker recognition domain, to show significant improvement over the standard learning 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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
