On Regularizing Effects of MINRES and MR-II for Large-Scale Symmetric Discrete Ill-Posed Problems [PDF]

Journal of Computational and Applied Mathematics, 320 (2017): 145-163, 2015
For large scale symmetric discrete ill-posed problems, MINRES and MR-II are often used iterative regularization solvers. We call a regularized solution best possible if it is at least as accurate as the best regularized solution obtained by the truncated singular value decomposition (TSVD) method.

An analysis and solution of ill-conditioning in physics-informed neural networks [PDF]

arXiv
Physics-informed neural networks (PINNs) have recently emerged as a novel and popular approach for solving forward and inverse problems involving partial differential equations (PDEs). However, achieving stable training and obtaining correct results remain a challenge in many cases, often attributed to the ill-conditioning of PINNs.
