| Abstract | Artificial neural nets have become very popular in various applications like pattern recognition, system identification and adaptive control. In general, a neural net is a nonlinear mapping device for function approximation in such a way that the arising error has to be minimized. This leads to an optimization problem where the cost function can be learned instead of being represented by a theoretical model. For that reason we have to discover the essential characteristics of the function to find its representation with minimal redundancy. Considering data compression there are similar requirements which have to be met. In this perspective, feature extraction as a basic capability of neural nets has to be performed for optimizing data compression. We consider wavelet transform coding because of its good fitting properties in both the time and frequency domains. Therefore, the choice of the wavelet is significant for a good fit of the signal and leads to an optimization problem which can be solved by a neural net. |

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.
