explaining the continuous time ddim sampling

[XavierXiao]

Hi! I am looking for a code for DDIM sampling when the noise scheduler is continuous, and I came to this repository. I have a question on https://github.com/crowsonkb/v-diffusion-jax/blob/master/diffusion/sampling.py#L11, since the model output is v, are you suggesting that the parametrization of the model is that the Unet output the signal to noise ratio, rather than eps? Thanks!
