Samson Gourevitch
I am a PhD student at École Polytechnique, advised by Professors Eric Moulines and Alain Durmus. My research focuses on generative modeling, mainly diffusion models, with a particular interest in discrete diffusion.
Recent paper Categorical Reparameterization with Denoising Diffusion Models
ReDGE introduces a diffusion-based soft reparameterization method for categorical distributions, with applications to latent variable models and guided discrete diffusion.
Recent note Doob’s h-transform and guided diffusion
An intuitive introduction to Doob’s h-transform and the way conditional Markov dynamics connect to guided diffusion models.
