Use the denoising step for those samplers when sigma goes to 0, instead of a sampler step. Although it looks like an Euler step, it is related to Tweedie’s formula. Without this, results can still easily appear blurry or noisy, even with more steps.
I also refactored the
gradient_estimationto simplify thed_barpart.
