Adaptive Moments are Surprisingly Effective for Plug-and-Play Diffusion Sampling

Christian Belardi, Justin Lovelace, Kilian Q. Weinberger +1

Guided diffusion sampling relies on approximating often intractable likelihood scores, which introduces significant noise into the sampling dynamics. We propose using adaptive mome…

On Speeding Up Language Model Evaluation

Jin Peng Zhou, Christian K. Belardi, Ruihan Wu +4

Developing prompt-based methods with Large Language Models (LLMs) requires making numerous decisions, which give rise to a combinatorial search problem over hyper-parameters. This…
