| Abstract | In this paper, we develop a comprehensive identification scheme for fuzzy relation-based neural networks (FRNNs). The proposed hybrid development approach combines the optimization technology of genetic algorithms (GAs) and an improved complex method introduced in the previous studies on fuzzy modeling. The structure of the FRNNs revolves around a collection of fuzzy rules and involves two types of fuzzy inference schemes. The taxonomy of these schemes relates to the format of the conclusion part of these rules (being either constants or linear functions). The optimization of the network deals with a number of essential parameters as well as the underlying learning mechanisms (e.g., apexes of membership functions, learning rates, and momentum coefficients). The hybrid identification approach helps achieve global optimization (when using GAs) and assure local convergence (that results from the use of the improved complex method). During the identification process, we are guided by a weighted objective function (performance index) in which a weighting factor is introduced to achieve a sound balance between approximation and generalization capabilities of the resulting model. The proposed identification method is applied to nonlinear processes (data) such as gas furnace process data and emission process data form a gas turbine power plant. The obtained experimental results show that the proposed networks exhibit high accuracy and generalization capabilities. |

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.
