Damped least square method
WebLeast squares, in general, is the problem of finding a vector x that is a local minimizer to a function that is a sum of squares, possibly subject to some constraints: min x ‖ F ( x ) ‖ 2 2 = min x ∑ i F i 2 ( x ) WebThe PSD III algorithm [10] is an improvement over the classic damped-least-squares (DLS) method of minimizing a merit function. The mathematics of that method is quite simple. It involves finding the derivatives of every operand in the merit function (a score whose value would be zero if the lens
