#011 Linear Algebra - Nonlinear Least Squares - Master Data Science 11.07.2021

Most of the time the equation of the model involves higher-order and higher-degree functions. In this post, we will learn how to solve the harder nonlinear equations using a heuristic algorithm of finding the least-squares approximate solution. Practically, almost all problems can be represented as a set of nonlinear equations. However, solving them is a little more complex than the method we used to apply for solving linear equations. Let us consider a set of \(m \) nonlinear equations and \(n \) variables.
