Ill-posed inversion problem

Web29 nov. 2024 · J. Baumeister, A. Leitao We investigate the iterative methods proposed by Maz'ya and Kozlov (see [KM1], [KM2]) for solving ill-posed inverse problems modeled by partial differential equations. We consider linear evolutionary problems of elliptic, hyperbolic and parabolic types. Web7 nov. 2008 · The EEG inverse problem is an ill-posed problem because for all admissible output voltages, the solution is non-unique (since p >> N) and unstable (the solution is highly sensitive to small changes in the noisy data). There are various methods to remedy the situation (see e.g. [ 7 – 9 ]).
