Gaussian Billboards: Expressive 2D Gaussian Splatting with Textures In this work we highlight the similarity between 2D Gaussian Splatting (2DGS) and billboards from traditional computer graphics. Both use flat semitransparent 2D geometry that is positioned, oriented...

No Training, No Problem: Rethinking Classifier-Free Guidance for Diffusion Models Classifier-free guidance (CFG) is widely used to improve conditional diffusion models, but it requires special training, and it doesn’t extend naturally to unconditional models. In this...
