| Abstract | Canonical polyadic decomposition (CPD) has been extensively studied and used in solving blind source separation (BSS) problems, mainly due to its nice identifiability property in mild conditions. In over-determined BSS and joint BSS (J-BSS), CPD is shown to be equivalent to tensor diagonalization (TD). In this study, we propose an algorithm for non-orthogonal TD (NTD) based on LU decomposition and successive rotations, and examine its applications in BSS and J-BSS. We use LU decomposition to convert the overall optimization into L and U stages, and then the factor matrices in these stages can be appropriately parameterized by a sequence of simple elementary triangular matrices, which can be solved analytically. We compared the proposed algorithm with orthogonal TD,tensor DIAgonalization (TEDIA) and CPD with simulations, the results show that in the over-determined case, NTD generates improved accuracy over TEDIA, CPD and orthogonal TD, and faster convergence than TEDIA. |

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.
