Latest Patents

One of Vahdat's latest patents focuses on synthesizing three-dimensional shapes using latent diffusion models in content generation systems and applications. This approach allows for the unconditional generation of novel 3D object shape representations, such as point clouds or meshes. In this patent, a first denoising diffusion model (DDM) is trained to synthesize a 1D shape latent from Gaussian noise, while a second DDM generates a set of latent points conditioned on this 1D shape latent. The generated shape latent and set of latent points can then be decoded to create a 3D point cloud representative of a random object from the trained object classes. Additionally, a surface reconstruction process can be employed to generate a surface mesh from the point cloud. This method is scalable to complex and multimodal distributions, making it highly adaptable for various tasks, including multimodal voxel- or text-guided synthesis.

Another notable patent by Vahdat involves denoising diffusion generative adversarial networks. This patent presents systems and techniques to train and utilize one or more neural networks. The denoising diffusion GAN reduces the number of denoising steps during a reverse process and does not assume a Gaussian distribution for large steps of the denoising process. By applying a multi-model approach, it allows for denoising with fewer steps, thus enabling faster sample generation from noise.
