| Abstract | Summary form only given. Epileptic seizures affect about 1% of the human population. Many patients (20%) are resistant to preventive drug treatment. The ability to anticipate the onset of seizures in such cases would permit clinical intervention. In previous work, the unsupervised optimal fuzzy clustering (UOFC) algorithm was applied to wavelet coefficient features in predicting hyperbaric-oxygen-induced generalized epileptic seizures in rat EEG. The two phases have the ability of processing and identifying transients (spikes), as well as long-term activity. In 16 instances, a pre-seizure state, lasting between 0.7 and 4 minutes, was defined. Projecting these results to human epilepsy is uncertain, given the different origin of the seizure as well as species differences in cerebral organization. In the present work, we attempt to predict spontaneous focal seizures in the EEG of epileptic patients who are monitored for surgical intervention. The UOFC is applied to two main classes of features: Fourier-transform based features (polyspectra) and multi-resolution based features (wavelets and multi-wavelets). Cluster formation shows the ability to detect 88%-100% of the 25 focal seizures and a prediction rate of in about 30% of the seizure, all using the wavelet coefficients as features. Less promising results were obtained using Fourier based features. |

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.
