Inverse Problems | SpringerLink

Inverse problems, are the opposite to forward ,problems,, meaning that one is given the effect and the task is to recover the cause. ,Inverse problems, do not necessarily have unique and stable solutions, i.e., they are often ill-posed in the sense of Hadamard [7].

Inverse problems - Department of Mathematics - The ...

Inverse problems, typically involve the recovery of some unknown parameters of a system from its response to an excitation such as electromagnetic fields, heat, or mechanical vibrations. ,Inverse problems, are often challenging since they are ill-posed, which means the process of recovering the unknown parameters is very sensitive to errors in the measured response.

Inverse Problems - IPGP

The first part of the course deals exclusively with discrete ,inverse problems, with a finite number of parameters. Some real ,problems, are naturally discrete, while others contain functions of a continuous variable and can be discretized if the functions under consideration are smooth enough compared to the sampling length, or if the functions can conveniently be described by their development ...
