A simple algorithm to find the L-curve corner in the regularization of inverse problems

16 Aug 2016 Alessandro Cultrera Luca Callegaro

We propose a simple algorithm devoted to locate the "corner" of an L-curve, a function often used to chose the correct regularization parameter for the solution of ill-posed problems. The algorithm involves the Menger curvature of a circumcircle and the golden section search method... (read more)
