Newton optimization method

Witryna10 lis 2014 · 3 Answers. The quick answer would be, because the Newton method is an higher order method, and thus builds better approximation of your function. But that is not all. Newton method typically exactly minimizes the second order approximation of a function f. That is, iteratively sets x ← x − [∇2f(x)] − 1∇f(x). Witryna• The work per iteration of Newton’s method is O(n3) • So-called “quasi-Newton methods” use approximations of H(xk)at each iteration in an attempt to do less work per iteration. 2 Proof of Theorem 1.1 The proof relies on the following two “elementary” facts. For the first√ fact,
