| Abstract | Introduces a novel algorithm for adjusting the structure of a Radial Basis Function Network (RBFN). It has been shown that Radial Basis Function Networks (RBFNs) are capable of universal approximation. This suggests the possibility of using these neural models to identify the chaotic systems. However, when one deals with the observable from some process (e.g., biological systems) whose mathematical formulation and the total number of variables may not be known exactly, structure construction and adjustment of the artificial neural network remain as an open question. In this work, the authors introduce the chaotic dynamics in the structure construction of the RBFN. It can be seen that the radial basis functions establish a partition of the embedding space into regions in each of which it is possible to approximate the dynamics with a basis function. On account of the fact that the attractor of the chaotic systems is a fractal object, the authors use the fractal scaling process for partitioning the strange attractor into self-similar structures. Accordingly, the number of input variables, the number of basis function, and the scaling parameter of the basis function can be specified by the fractal scaling process. This work represents a promising approach to the modeling and prediction of chaotic time series. |

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.
