We consider guiding denoising diffusion models with general differentiable loss functions in
a plug-and-play fashion, enabling controllable generation without additional training. This …

Score-based diffusion models provide a powerful way to model images using the gradient of
the data distribution. Leveraging the learned score function as a prior, here we introduce a …

Deep MRI reconstruction is commonly performed with conditional models that de-alias
undersampled acquisitions to recover images consistent with fully-sampled data. Since …

Image deblurring is an ill-posed problem with multiple plausible solutions for a given input
image. However, most existing methods produce a deterministic estimate of the clean image …
