Conditioning signal in Diffusion ProjectedGAN

[Zhendong-Wang]

Hi there, thanks for your interest and sorry for the late reply. Empirically we found the discriminator in ProjectedGAN doesn't need the $t$ as the condition. The discriminator in ProjectedGAN is different from StyleGAN2, which is light-weighed. Injection of $t$ will support our Theorem 2 but sometimes without $t$ condition, the algorithm still works.

Thank you for your reply!

Yes, this is surprising to me. Now, I understand that you empirically found the algorithm works even without $t$.
