Lecture 13.1: all around Newton's method
Aggregazione dei criteri
More on Newton's method: interpretations (linearization of the nonlinear system on the gradient, gradient method in the modified space), convergence properties. A bird's eye on trust region methods. Newton's method in practice: the role of the \delta parameter (often none, but not always). Take away: Newton's method can work with something that can be "quite different" from the true Hessian, although it should be "related".
