| Abstract | Due to wavelet network with the advantage of multi-scale of wavelet and self-learning of neural network, it is widely applied in regression estimation. But it is seriously affected by the samples with gross error. Although M-estimation as object function can be used to solve the problem, its corresponding influence function is determined by the absolute value of error, thus a key problem is to choose initial parameters. In this paper, we propose an estimation method for regression function based on multiwavelet support vector machine (SVM). This method firstly puts forward and proves a new wavelet SVM used to determine initial parameters. It can determine reasonable network structure and appropriate initial parameters, which makes sure that there is bigger absolute value of residual error of samples with gross error. Then M-estimation is used as object function and the method used to determine the threshold is put forward. Simulation results show that regression model obtained with this proposed method not only has better approximation precision, but also improves robustness and generalization. It is conduced to widening the application for wavelet network. |

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.
