They address that paper specifically here: "GQN uses analysis-by-synthesis to perform “inverse graphics,” but unlike existing methods (42), which require problem-specific engineering in the design of their generators, GQN learns this behavior by itself and in a generally applicable manner. However, the resulting representations are no longer directly interpretable by humans."
