* Title: An inverse problem in random matrix theory and free probability theory. *

* Abstract:
Matrix valued free probability theory makes it possible to compute
analytically or numerically the eigenvalue distributions of mixtures of
large random matrices and deterministic ones.
This talk introduces its inverse problem: how to estimate parameters (e.
g. deterministic matrices) of a random matrix model from the sampled
empirical eigenvalue distributions.
No knowledge on free probability or random matrices is assumed for the talk.*
