| Abstract | Summary form only given, as follows. The author explores the concept of influence functions and their application in backpropagation learning. One reason for backpropagation's popularity is the fact that it is capable of fitting functions involving high-order interactions. Most real problems not only require detecting nonlinear interactions, but in many cases involve fitting relationships which are contaminated by diverse noise conditions. Typically, backpropagation learning is achieved by minimizing the sum of squared errors. It is well known that least-squares estimators are maximally efficient when the noise is Gaussian but that their performance rapidly deteriorates under non-Gaussian noise. The author's objective is to make backpropagation resistant to various types of noise. This approach uses objective functions which, in other contexts, are known to be more robust than least squares. Simulations show that backpropagation with robust objective functions indeed learns well and generates solutions that are resistant to a wide variety of noise distributions. |

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.
