@lucidrains Hi, is this implementation above equivalent of DDIM sampler for continuous time?
Hi @markub3327 did you ever manage to implement DDIM for continuous time? I am also interested in this
@lucidrains Yes, I'm. Why you asking? Did you known something new?
@markub3327 It would be great if you can share the implementation because I also tried something similar but I am unable to make this work - Or what you posted here worked well for you?
I also tried squaring the alpha and alpha next but still the results are poor...
@danbochman Hi, I don't have any else implementation, that is above. And the results I get better with discrete timestep by this implementation. Here is the DDIM sampler with continuous time which may be working well: https://keras.io/examples/generative/ddim/
Hello,
is possible to use the DDIM sampler when the time is continuous (continuous_time_gaussian_diffusion.py)? Please can you provide a simple example of code?
I try to implement it like this (scheduling_ddim.py):
The only issue with this implementation is how calculate the
self.alphas_cumprod
. Or this is not a good way of thinking?Thanks.
