| Abstract | A new learning algorithm is introduced that can accommodate data with missing features. The algorithm uses an ensemble of classifiers approach. The classifiers in the ensemble are trained with random subsets of the total number of available features. The approach takes advantage of the basic assumption that an unknown subset of the features is in fact adequate for the classification, or in other words, that are redundant, and possibly irrelevant features in the data. This assumption is in general true for most practical applications. We empirically show that if a certain number of networks produce a particular classification performance using all of the features, then the same classification performance can be reached even if some features are missing, as long as the same number of usable networks can be generated with the missing features. The proposed approach has its roots in the incremental learning algorithm, Learn/sup ++/ which seeks to learn new information that is provided by additional datasets that may later become available, even when such data introduce new classes. We have modified the Learn/sup ++/ algorithm for addressing the missing feature problem. The proposed algorithm showed surprisingly remarkable performance on three real-world applications, with up to 10% of the features missing in the validation / field data. |

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.
