Generative modeling by estimating gradients
WebFeb 1, 2024 · Abstract. We present a novel deep generative model based on non i.i.d. variational autoencoders that captures global dependencies among observations in a fully unsupervised fashion. In contrast to the recent semi-supervised alternatives for global modeling in deep generative models, our approach combines a mixture model in the … Web[2] Yang Song and Stefano Ermon Generative modeling by estimating gradients of the data distribution In: Advances in Neural Information Processing Systems 2024 [3] Jonathan Ho, Ajay Jain and Pieter Abbeel Denoising diffusion probabilistic models In: Advances in Neural Information Processing Systems 2024
