Can we apply diffusion directly on MLP weights? Yes!!! We show generalization to new 3D shapes and 4D mesh animations: "HyperDiffusion: Generating Implicit Neural Fields with Weight-Space Diffusion" #ICCV2023! Project: Video:

Quite interesting that neural fields can be directly used as representations for generative models. One open question is what MLP weight structure works best for generalization. Super cool work by @ErkocZiya in collaboration with @angelaqdai, @fangchangma, and Qi Shan.

@CasualEffects Cool idea.

We had a similar idea in our brainstorming sessions, curious to read in detail. Sounds excellent!!

Very cool work! How does it compare with MeshDiffusion whose geometric representation is more explicit?

Potential technologies. Thanks for the info!

One question: why not generate triplane representation? since it more straightforward for diffusion models.
