Newton's method in optimization. A comparison of gradient descent (green) and Newton's method (red) for minimizing a function (with small step sizes). Newton's method uses curvature information (i.e. the second derivative) to take a more direct route. In calculus, Newton's method is an iterative method for … Zobacz więcej In calculus, Newton's method is an iterative method for finding the roots of a differentiable function F, which are solutions to the equation F (x) = 0. As such, Newton's method can be applied to the derivative f … Zobacz więcej The central problem of optimization is minimization of functions. Let us first consider the case of univariate functions, i.e., functions of a single real variable. We will later … Zobacz więcej Finding the inverse of the Hessian in high dimensions to compute the Newton direction $${\displaystyle h=-(f''(x_{k}))^{-1}f'(x_{k})}$$ can be an expensive operation. In … Zobacz więcej • Quasi-Newton method • Gradient descent • Gauss–Newton algorithm Zobacz więcej The geometric interpretation of Newton's method is that at each iteration, it amounts to the fitting of a parabola to the graph of Zobacz więcej If f is a strongly convex function with Lipschitz Hessian, then provided that $${\displaystyle x_{0}}$$ is close enough to $${\displaystyle x_{*}=\arg \min f(x)}$$, the sequence Zobacz więcej Newton's method, in its original version, has several caveats: 1. It does not work if the Hessian is not invertible.
