Figure 3
A graphical representation of random raster subsampling combined with the LoopedASD algorithm. Random raster sampling results in a dataset where the measurements correspond to blocks of entries for each row (left side). The LoopedASD algorithm aims to find two factors $[{\bf{X}}]$ and $[{\bf{Y}}]$ so that $[{\bf{XY}}]$ fits the observed measurements: $[{\cal P}({\bf{D}})]$ ≃ $[{\cal P}({\bf{XY}})]$ .
