| Abstract | This paper suggests and compares two approaches for building a fuzzy-rule based system for time series modeling and forecasting. The first one is based on a constructive offline learning (C-FSM). The second one, is based on an adaptive online learning process (A-FSM). Both models have its general architecture based on a fuzzy rule based system, and its respective learning algorithms are based on the EM optimization technique. Because the C-FSM is trained in an offline learning, it results in a more accurate model. However, the A-FSM has a faster learning process, since it is not necessary to retrain it with all data available at each iteration. The A-FSM also provides a more compact structure, being its learning and structure generation, great advantages in terms of time process and computational effort, when compared to the constructive approach. Results applying both techniques for building time series models show their efficiency, having each one of them important advantages when compared. The constructive offline model gets better accuracy, but, the online one, has a faster learning and a provides a simpler final structure. |

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.
