| Abstract | Most of market demands are greatly dynamically changed such as in finance, industries and etc. In order to adapt to the highly dynamic changes of market and reduce cost and risk, we need to develop effective management strategies based on accurate market demand forecast. Many of the traditional forecasting methods, such as the neural network, ARIMA, which based on historical data, cannot find out the hidden remarkable features behind the data, thereby affecting the accuracy of forecasting. In this paper, ICA as one of the most popular signal decomposition technologies in recent years is introduced to excavate the potential information of market for better prediction of dynamic changes in market demand and mining of margin customer, where ICA plays an important role of preprocessing. The experiments show that the prediction based on ICA preprocessing is superior to direct prediction by neural network, and successful to excavate potential customers for better market directing. In addition, we also address the essential difference of dimension reduction using PCA and ICA, show that these two approaches are different at the aspect of sensitivity to dimensions although they both are pre-processing methods of dynamic data, even if the accumulative contribution rate of ICA is 7.4% less than that of PCA, the former still attains the same prediction results as the latter. |

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.
