WebFeb 22, 2011 · 0. The fastest, most efficient way to solve least squares, as far as I am aware, is to subtract (the gradient)/ (the 2nd order gradient) from your parameter vector. (2nd order gradient = i.e. the diagonal of the Hessian.) Here is the intuition: Let's say you want to optimize least squares over a single parameter. WebAlso called as the tangent line approximation, the tangent line is is used to approximate the function. The Linear Approximation formula of function f (x) is: f ( x) ≈ f ( x 0) + f ′ ( x 0) ( x − x 0) Where, f (x 0) is the value of f (x) at x = x 0. f' (x 0) is the derivative value of f (x) at x = x 0.
