In numerical optimization, the Broyden–Fletcher–Goldfarb–Shanno (BFGS) algorithm is an iterative method for solving unconstrained nonlinear optimization problems. Like the related Davidon–Fletcher–Powell method, BFGS determines the descent direction by preconditioning the gradient with curvature information. It does so by gradually improving an approximation to the Hessian matrix of the loss function, obtained only from gradient evaluations (or approximate grad… WebSep 27, 2024 · Photo by Christian Bowen on Unsplash Table of Contents (read till the end to see how you can get the complete python code of this story) · Conjugate Gradient for Solving a Linear System · Improving the Algorithm ∘ Theorem ∘ Simple Problems · Conjugate Gradient for Nonlinear Optimization Problem ∘ Wolfe Line Search ∘ …
