| Abstract | Resource-constrained data mining introduces many constraints when learning from large datasets. It is often not practical or possible to keep the entire data set in main memory and often the data could be observed in a single run in the order in which they are presented. Traditional reservoir-based approaches perform well in this situation. One drawback of these approaches is that the examples not included in the final reservoir are often ignored. To remedy this situation we propose a modification to the baseline reservoir algorithm. Instead of keeping the actual target values of reservoir examples, an estimate of their conditional expectation is kept and updated online as new data are observed from the stream. The estimate is obtained by averaging target values of the similar examples. The proposed algorithm uses a paired t-test to determine the similarity threshold. Thorough evaluation on generated two dimensional data shows that the proposed algorithm is producing reservoirs with considerably reduced target noise. This property allows training of significantly improved prediction models as compared with the baseline reservoir-based approach. |

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.
