Abstract | Presents a fast training algorithm with which one can sequentially determine the needed hidden nodes and the values of the associated weights for classification and pattern recognition. This new approach addresses problems in backpropagation and other gradient descent training algorithms. These problems include long training times, and the determination of the proper number of hidden nodes. We mitigate these difficulties by sequentially extracting important attributes of the training data in training each hidden node. The proposed algorithm separates the network training into the training of each layer of the network. The input layer is designed to partition the input data space using linear discriminant functions. The training starts from one hidden node. By applying a linear discriminant algorithm, a separable subset of the data is deleted from the training set. The remaining data is carried over to the training of the next hidden nodes. A hidden node is added to the network when it is needed because the classification performance on the training set is not yet good enough. Thus the training data set is reduced sequentially while the training is in progress. Each node of the output layer performs a logic function of the binary outputs of the hidden nodes. The training algorithm for the output layer is same as Boolean minimization. |

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.
