\(L\)-curve curvature bounds via Lanczos bidiagonalization
Electronic transactions on numerical analysis, Tome 14 (2002), pp. 20-35
The L-curve is often applied to determine a suitable value of the regularization parameter when solving ill-conditioned linear systems of equations with a right-hand side contaminated by errors of unknown norm.
Keywords: ill-posed problem, regularization, L-curve, Gauss quadrature
