11. For example, the least-squares method can be viewed as a very simple form of regularization. 12. One example of a maximum likelihood method commonly used in engineering is the least squares method . 13. LOESS is also prone to the effects of outliers in the data set, like other least squares methods . 14. Orthogonalization methods ( such as QR factorization ) are common, for example, when solving problems by least squares methods . 15. In computer graphics, the moving least squares method is useful for reconstructing a surface from a set of points. 16. A simple pen-and-paper method for generating random numbers is the so-called middle square method suggested by John von Neumann. 17. Once the surveyor has calculated the level of the errors in his work, it is Principle of least squares method . 18. The method of least absolute deviations finds applications in many areas, due to its robustness compared to the least squares method . 19. The least-squares method is usually credited to Carl Friedrich Gauss ( 1795 ), but it was first published by Adrien-Marie Legendre. 20. At the next step, the initial segmentation is refined by fitting quadratics whose coefficients are calculated based on the Least squares method .
