| Abstract | Sequential Monte Carlo methods (Particle Filters) have been successfully applied to the online training of neural networks. However the generic Particle Filter requires the model noise to be known prior to training. Furthermore, the random walk assumption with which the network weights are modeled by may be problematic as a result of the insufficient knowledge of the model noise. In this paper, the evolution of the network weights are modeled using the Polynomial Prediction Model (PPM) which has been shown to have more predictive power than the random walk. The PPM can generate a whole class of models which can then be used in a modified multimodel version of the Particle Filter based on the Interacting Multiple Model (IMM) to train the neural network. The resulting algorithm generates an estimate of the noise terms which is closer to the true noise in the form of a weighted linear combination of the model noise given in the different models. This means that the algorithm can adapt to unknown model noise. Experiments show that the proposed algorithm offers better performance in training neural networks in the context where we are unable to determine the error terms. |

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.
