| Abstract | The brain is one of nonlinear systems. EEG (electroencephalogram) is widely used to monitor the brain condition. Frequency analysis method is given as general EEG analysis method. DR analysis is to evaluate the deviation ratio of power spectrum of arbitrary frequency band. On the other hand, neural networks are used to analyze nonlinear systems because of their ability to capture the dynamics of complex system. In this study, we propose the application of moving average-type neural networks (MANN) to analyze the EEG and compare the result of MANN analysis with the one of DR analysis. In this time, we used the randomness to optimize the number of input units of MANNs. In MANN analysis method, the measured EEG is divided into overlapped period 20 seconds. A MANN is trained to predict the EEG using three previous samples in each period. After training, the connecting weights of each MANN are compared using the inner product to evaluate changes in brain condition. We used measured EEG in closing/opening eyes to analyze. According to the results, the usefulness of MANN analysis was confirmed. And MANN analysis has possibility to be able to apply to analysis of the other EEG data or the other nonlinear systems. |

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.
