I've been using the powermethod (since it does not require matrix inversion) for computing the largest eigenvalue but in some cases it is extremely slow probably due the ratio of eigenvalues lamda2/lamda1 being close to 1. Can anyone suggest a better ...
Our second contribution is a matrix-free algorithm to find a minimizer of the regularized reaper which is also suited for high-dimensional data. The algorithm couples a primal-dual minimization approach with a thick-restarted Lanczos process. This appears to be the first efficient convex variational...
In this paper, we introduce a new iterative algorithm for solving a generalized Sylvester matrix equation of the formwhich includes a class of linear matrix equations. The objective of the algorithm is to minimize an error at each iteration by the idea of gradient-descent. We show that the pr...

A New Restarting Method In The Arnoldi Algorithm For Computing The Eigenvalues Of A Nonsymmetric Matrix 作者: Najafi, HS;Khaleghi, E;摘要: We have developed a new restarting method called "minimum restarting method". The choice of the initial vector in this procedure is different from all the ...
It is not at all obvious, but this matrix has been constructed to have eigenvalues 1, 2, and 3. The first iteration of our one-line QR code produces A = 28.8263 -259.8671 773.9292 1.0353 -8.6686 33.1759 -0.5973 5.5786 -14.1578 The matrix is now much nearer to being upper triangular, ...
Finding the ground state of a quantum many-body system is a fundamental problem in quantum physics. In this work, we give a classical machine learning (ML) algorithm for predicting ground state properties with an inductive bias encoding geometric localit

We analyze the mathematical structure of the classical Grover’s algorithm and put it within the framework of linear algebra over the complex numbers.
