Webb21 aug. 2024 · Now, methods like BFGS, are quasi-Newton methods. Quasi-Newton methods also try to avoid using the Hessian directly, but instead they work to approx. it by (in the case of BFGS), progressively updating an approx. per iteration. This is shown below, where B is approximate Hessian (taken from wiki) Webb1 apr. 2012 · The algorithm uses a BFGS update of the Gauss-Newton Hessian when some hueristics indicate that the Gauss-Newton method may not make a good step. ...

Webbimplicitly a reformulation of the Gauss-Newton method (see Section 3.1 for details) which is a classic second-order algorithm often used for solving nonlinear regression problems with square loss. In the Gauss-Newton method, one uses J>J as an approximation of the Hessian (see Section 2 for a formal description) where J is the Jacobian matrix.
