Is the GAN architecture better suited for medical image denoising than the CNN?
I'm considering using GANs for medical image denoising, based on previous literature, like this and this. My input to the GAN would be a high-noise image and my ideal output would be a low-noise, high-quality image.
Is the GAN architecture better…

Reverse Distribution in Denoising Diffusion Models is Simple
In explanations of denoising diffusion models it is stated that $q(x_{t-1}|x_t)$ is intractable. This is often justified via Bayes' rule, i.e.
$$
q(x_{t-1}|x_t) \propto q(x_t|x_{t-1})q(x_{t-1})
$$
and the marginal $q(x_{t-1})$ is unknown. But I'm…
