Abstract | The input weight and the bias of hidden layer nodes are randomly generated in the training process of the traditional Extreme Learning Machine (ELM), which is simple and with no need for repeated iteration, thus the model training speed increases significantly. However, this algorithm model possesses a defect that it's difficult to choose a reasonable network structure for users due to the parameters which are randomly generated each time can not guarantee high accuracy. For the requirements on rapidity and accuracy of ELM, an improved ELM model is proposed in this paper, the sine function data and its variants function data are adopted to be as the training sample and testing sample. The algorithm execution of generating two paremeters randomly has been circulated n times by defining cycle number n, and then a group of parameters with highest accuracy are automatically selected from the n cycles. Experimental results show that, compared with traditional ELM, the model accuracy of the proposed scheme improves greatly; then compared with BP neural network, the improved ELM model in this paper has great advantage in training speed, and also can achieve very high precision in accuracy. |

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.
