In a previous post, we explored the popular steepest descent method for optimization and implemented it from scratch in Python:

In this article, we aim to introduce Newton’s method and share a step-by-step implementation while comparing it with the steepest descent.

Optimization is the process of finding the set of variables x that minimizes an objective function f(x):

To solve this problem, we can select a starting point in the coordinate space and iteratively move toward a better approximation of… Read the full blog for free on Medium.
