In linear algebra, the singular value decomposition (SVD) is a factorization of a real or complex matrix into a rotation, followed by a rescaling followed by another rotation. It generalizes the eigendecomposition of a square normal matrix with an orthonormal eigenbasis to any m × n {\displaystyle m\times n} matrix.
The Society of the Divine Word (Latin: Societas Verbi Divini), abbreviated SVD and popularly called the Verbites or the Divine Word Missionaries, and sometimes the Steyler Missionaries, is a Catholic clerical religious congregation of Pontifical Right for men.
In linear algebra, the generalized singular value decomposition (GSVD) is the name of two different techniques based on the singular value decomposition (SVD).The two versions differ because one version decomposes two matrices (somewhat like the higher-order or tensor SVD) and the other version uses a set of constraints imposed on the left and right singular vectors of a single-matrix SVD.
The SVD decomposes M into three simple transformations: a rotation V *, a scaling Σ along the rotated coordinate axes and a second rotation U. Σ is a (square, in this example) diagonal matrix containing in its diagonal the singular values of M , which represent the lengths σ 1 and σ 2 of the semi-axes of the ellipse.
The term higher order singular value decomposition (HOSVD) was coined be DeLathauwer, but the algorithm referred to commonly in the literature as the HOSVD and attributed to either Tucker or DeLathauwer was developed by Vasilescu and Terzopoulos. [6] [7] [8] Robust and L1-norm-based variants of HOSVD have also been proposed. [9] [10] [11] [12]
Arnold Janssen SVD (5 November 1837 – 15 January 1909), was a German-Dutch Catholic priest and missionary who is venerated as a saint.He founded the Society of the Divine Word, a Catholic missionary religious congregation, also known as the Divine Word Missionaries, as well as two congregations for women.
Latent semantic indexing (LSI) is an indexing and retrieval method that uses a mathematical technique called singular value decomposition (SVD) to identify patterns in the relationships between the terms and concepts contained in an unstructured collection of text. LSI is based on the principle that words that are used in the same contexts tend ...
Marian Żelazek (30 January 1918 – 30 April 2006) was a Polish Roman Catholic priest of the Society of the Divine Word (SVD) who lived in India and served amongst the people of Orissa. He is remembered for his service and care towards the lepers in the region. He was the last foreign missionary of the SVD congregation in India.
