Damped least square method
WebAbstract. A modification introduced in the damped least-squares method automatically assigns a damping factor to each parameter in a manner that compensates for the … 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 non-zero damping constant.
