Reconstruction of the factors matrix for the Hemoglobin data. Shown are (a) the true profiles of OxyHb, MetHb and CyanoHb, (b) the reconstructed profiles given by algorithm F, (c) the reconstructed profiles given by algorithm W, (d) the reconstructed profiles given by algorithm GNCA, and (e) the reconstructed profiles given by algorithm GNCA_r. The positions of the zero entries in the loadings matrix are given a priori. The light gray curves are the profiles given by the 20 different Gibbs sampling runs, and the black curves are the average profiles. In these figures, the average profile of each factor coincides with its profile given by each single run.
