Matrix inversion lemma

2 A Characterization of Symmetric Positive De nite Another useful matrix inversion lemma goes under the name of Woodbury matrix identity, which is presented in the following proposition. Proposition Let be a invertible matrix, and two matrices, and an invertible matrix. If is invertible, then is invertible and its inverse is. Proof. Gradient Descent Methods for Type-2 Fuzzy Neural Networks. Erdal Kayacan, Mojtaba Ahmadieh … Matrix inversion lemmas The Woodbury formula is maybe one of the most ubiquitous trick in basic linear algebra: it starts with the explicit formula for the inverse of a block 2x2 matrix and results in identities that can be used in kernel theory, the Kalman filter, to combine multivariate normals etc. In this article we’ll derive the matrix inversion lemma, also known as the Sherman-Morrisson-Woodbury formula.
