WebMar 31, 2024 · Start from initial guess for your solution. Repeat: (1) Linearize r ( x) around current guess x ( k). This can be accomplished by using a Taylor series and calculus (standard Gauss-Newton), or one can use a least-squares fit to the line. (2) Solve least squares for linearized objective, get x ( k + 1). Web3. The Gauss-Newton Method The Gauss-Newton method is based on the basic equation from New-ton’s method (1.1), except that it uses a search direction vector pGN k and a step size k in the revised equation (3.1) x k+1 = x k + kp k: The values that are being altered in this case are the variables of the model function ˚(x;t j).
