📢Text-to-3D generation via score distillation (DreamFusion, ProlificDreamer, etc.) produces high-quality 3D assets, but can take up to 10 hours to run. We present an acceleration method for all existing approaches based on score distillation and achieves up to 4.7x speedup.

📢 Diffusion models (DM) generate samples from noise distribution, but for tasks such as image-to-image translation, one side is no longer noise. We present Denoising Diffusion Bridge Models, a simple and scalable extension to DMs suitable for distribution translation problems.
