Damped least-squares method
WebThe damped least squares (DLS) method avoids many of the pseudo-inverse method’s problems with singularities; it was flrst used for inverse kinematics by [8, 7]. DLS works by flnding the value of ¢µ that minimizes the quantity jjJ¢µ ¡~ejj2 + ‚2jj¢µjj2, where ‚>0 is a … WebThe three least-squares normal equations for hypocentral coordinates, with diagonal terms equal to one, are then solved iteratively by adding a variable damping factor, θ 2, to their diagonal terms before inversion. If the residual sum of squares increases, we return to the previous iteration, increase θ 2, then try again. This procedure ...
