| Abstract | For monitoring any system, be it a chemical plant, a nuclear power station, or a human heart or brain, we need to attach sensors and analyze the multivariate time-series data collected by those sensors. If the system has two states, say state 1 (good) and state 2 (bad), we need to infer which state the system is, by classifying the collected time-series signals. To make this work efficiently, it is important to search the least number of probes that would give best classification result. It is a multi-objective optimization problem. The proposed approach works in two steps. We start with a large number of probes. As the first step, we cluster the time-series signals. and choose a representative one from each cluster. Next, we run pareto GA to select the smallest set of probes (from cluster representatives), that would give the highest classification result. Depending on the nature of the signals, and the target application, appropriate signal-features, clustering and classification algorithms will be different, but the basic principle is applicable to any system. In this paper, we tested the effectiveness of our algorithm with EEG signals, to detect the presence or absence of ERP 300. Improved results with less number of probes compared with previous works validated the approach. |

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.
