WebThe Newton-Gauss method of using first order Taylor expansions to yield linear normal equations is well known in the theory of non-linear regression and in the solution of non-linear simultaneous equations. The procedure of 'damped least squares' was introduced by Levenberg' in order to improve the approximations, the point being that, without the WebJul 1, 2008 · The second method is an extension of damped least squares called selectively damped least squares (SDLS), which adjusts the damping factor separately for each singular vector of the Jacobian ...
