| Abstract | Data filtering methods are so much crucial to get good performance in time series forecasting. There are a few preprocessing methods (i.e. ARMA outputs as time domain filters, and Fourier transform or wavelet transform as time-frequency domain filters) for handling time series. In particular, the time-frequency domain filters describe the fractal structure of financial markets better than the time domain filters without frequency information. We study the issues of integrated methods of joint time frequency analysis and neural network techniques as the application of multi-cyclic decomposition methods to the neural networks for short-term point forecast decision making The issues include the appropriate selection of neural network model architecture, for example, what type of neural network learning architecture is selected and what input size should be selected for our time series forecasting. We analyze these problems in particular with recurrent neural network learning and embedding dimension as chaos analysis. This study is also applied to a case study of daily Korean won/U.S. dollar exchange returns. Finally we suggest an integration framework for future research from our experimental results. |

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.
