Abstract | The paper presents new hybrid procedure for analog circuit fault clustering with the use of simulated annealing and self-organizing neural network. Main goal of the method is to find best PWL excitation under maximum diagnosability of the circuit. Optimization is done with simulated annealing. For each node in the optimization the goal function ranks how well a neural network performs in the classification of the circuit of interest. The testing procedure is performed in time domain and therefore simulated annealing optimizes piece wise linear (PWL) excitation. The neural network input data comes from the circuit test point(s). Self-organizing map (SOM) has been applied in order to cluster all circuit states into possible separate groups. So, it works as a feature selector and classifier. The procedure has been applied for ECG amplifier and then results have been evaluated. The hybrid approach shows good efficiency in reasonable time. |

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.
