| Abstract | Manifold learning algorithms, such as ISOMAP, LLE, Laplacian Eigenmaps, LTSA and so on, are designed to map nonlinear high dimensional data into the low dimensional space. The key of their success is to select a suitable neighborhood parameter. However, it is difficult to determine a proper neighborhood size for most of manifold learning methods, in particular for non-uniform data sets. An adaptive manifold learning algorithm based on ISOMAP is presented to solve the problem by combining two methods of building the neighborhoods. In the method, all points within a fixed radius are taken as the neighborhood candidate points. The data point number contained in the neighborhood is constricted to a more proper range by setting a minimum value and a maximum value containing points in the neighborhood. Experiments show that the proposed algorithm is effective for the uniform data sets as well as the non-uniform data sets. Moreover, the difficulty of selecting the neighborhood parameter is greatly degraded. |

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.
