| Abstract | A novel multi-attribute sparse representation enforced with group constraints is proposed in this paper. Data with multiple attributes can be represented by individual binary matrices to indicate the group properties for each data sample. Then, these attribute matrices are incorporated into the formulation of $l_{1}-minimization.$ The solution is obtained by jointly considering the data reconstruction error, the sparsity property as well as the group constraints, thus making the basis selection in sparse coding more efficient in term of accuracy. The proposed optimization formulation with group constraints is simple yet very efficient for classification problems with multiple attributes. In addition, it can be derived into a modified sparse coding form so that any $l_{1}-minimization$ solver can be employed in the corresponding optimization problem. We demonstrate the performance of the proposed multi-attribute sparse representation algorithm through experiments on face recognition with different kinds of variations. Experimental results show that the proposed method is very competitive compared to the state-of-the-art methods. |

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.
