dc.description |
This paper proposes a very fast method for blindly approximating a nonlinear mapping
which transforms a sum of random variables. The estimation is surprisingly
good even when the basic assumption is not satisfied.We use the method for providing
a good initialization for inverting post-nonlinear mixtures and Wiener systems.
Experiments show that the algorithm speed is strongly improved and the asymptotic
performance is preserved with a very low extra computational cost. |
