Exactly what i think!

- The DDN single-shot generator architecture is more efficient than diffusion.

- DDN is fully end-to-end differentiable, allowing for more efficient optimization when integrated with discriminative models or reinforcement learning.

- Moreover, DDN inherently avoids mode collapse.
