| Abstract | Seizure detection with EEG analysis in the form of offline is an application of brain signal processing. In this paper, a seizure detection algorithm using pattern features of periodogram and an optimized hybrid model based on Ant Colony Optimization (ACO) and Multi-Layer Perceptron (MLP) neural network is proposed. In this algorithm, with introducing a novel feature extraction method, a feature vector based on periodogram is extracted. For this purpose, we define a novel color map of periodogram pattern based on windowing method and modified periodogram. Statistical and frequency features are computed for each one of five rhythms in EEG signals. These rhythms and features are extracted by using a novel scenario that is called Periodogram Pattern Feature (PPF). In this scenario, at first by making a color pattern of periodogram as an estimation of the spectral density, for each signal, a Time-Frequency layout is created. This pattern is divided to some epochs for decomposing the brain rhythms. Also, to optimize the feature vector, ACO algorithm in combination with MLP is used. At last, a perfect set of features with 5 valid items has provided. Moreover, seizure from non-seizure signal has been classified with accuracy of 94.4% using the final optimized 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.
