Abstract:	The disk integration process in Doppler imaging and Zeeman-Doppler imaging requires excessive calculations of local Stokes profiles and thus has high computational demands. We present a novel approximation method for the polarized radiative transfer calculation, base on a Principal Component Analysis and Artificial Neural Networks. A set of local line profiles is decomposed into their respective eigenspectra and Artificial Neural Networks are trained, to approximate the non-linear mapping between atmospheric parameters and principal components. In test calculations we demonstrate the reliability and precision of this fast radiative transfer approximation method.
