pip install -r requirements.txt
python3 main.py config/ring.yml train
This command produces the model (learnt scaled score function): ring.pth
python3 main.py config/ring.yml test
This command produces a list of frames at each stage of sampling under ring/ and an animation ring.gif made from them.
- Left: sample from the real pixel distribution
- Right: sample using Langevin dynamics based on the score function learnt via denoising score matching.
- A good lecture on Langevin dynamics for sampling.
- A recent paper combining Langevin dynamics with denosing score matching with a more complicated multi-level pertubation scheme.
- A paper introducing the denoising score matching.
