Diffusion Schrödinger Bridges for Bayesian Computation

Jeremy Heng, Valentin De Bortoli, Arnaud Doucet

Denoising diffusion models are a novel class of generative models that have recently become extremely popular in machine learning. In this paper, we describe how such ideas can als…

Reinforced Self-Training (ReST) for Language Modeling

Caglar Gulcehre, Tom Le Paine, Srivatsan Srinivasan +11

Reinforcement learning from human feedback (RLHF) can improve the quality of large language model's (LLM) outputs by aligning them with human preferences. We propose a simple algor…

A Unified Framework for U-Net Design and Analysis

Christopher Williams, Fabian Falck, George Deligiannidis +3

U-Nets are a go-to, state-of-the-art neural architecture across numerous tasks for continuous signals on a square such as images and Partial Differential Equations (PDE), however t…
