WebFeb 28, 2024 · At the very least, Newton’s method requires that ∇2f(x) is positive definite for every x ∈ R d, which in particular implies that there exists a unique optimal solution x∗. However, this is not enough to guarantee convergence, as the following example illustrates. Example 1.1 Consider f(x) = √ 1+x2 defined over the real line. The ... WebFor this example, the vector y was chosen so that the model would be a good fit to the data, and hence we would expect the Gauss-Newton method to perform much like …
