| Abstract | Recurrent neural networks are suitable for solving problems with temporal extent e.g. speech recognition, time series prediction, sequence generation. The biggest problem is, however, its computational complexity during the training process. Using the well-known real time recurrent learning rule of Zipser and William (1989), the training time of each epoch is of order O(n/sup 4/) where n is the total number of hidden units and output units. To cope with this low efficiency, the authors have devised a new network model called the partially connected recurrent network. Using the modified learning rule, the computational complexity of training becomes only O(mn+np), where m is number of outputs and p is the number of external inputs. In addition this new recurrent model is very suitable for running on a regularly connected SIMD parallel computer since each neuron needs only to communicate with those connected to it directly. The authors have verified this idea by implementing both a ring-structured recurrent network and a grid-structured recurrent network on the DECmpp 12000Sx System with 8192 processors. It can be shown that the training time per epoch now increases only linearly, i.e. O(m+n+p), which is a big advantage for solving large scale problems. |

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.
