✨ News

• 2022-2-04: The official JMLR version is now available online.
• 2021-12-01: The comprehensive version of this work was accepted to Journal of Machine Learning Research (JMLR)!
• 2021-11-11: Release the full version with new applications of sparse-view CT (ct) and single-photon imaging (spi).
• 2021-9-25: Release the initial version. It now includes all sources (code and data) to reproduce our results on the ICML paper. More applications (presented on our journal version) are coming soon.

Requirement

• Pytorch <= 1.7

Getting Started

Clone the repo, and install the tfpnp package first. For developing purpose, you are recommended to install the package with -e option.

git clone https://github.com/Vandermode/TFPnP.git
cd TFPnP
pip install -e .

Testing

1. Download the test data and pretrained models (checkpoints and denoiser) from Link, unzip and put them into tasks/[task]/data, tasks/[task]/checkpoints and tfpnp/pnp/denoiser/pretrained
2. Run the test via the following command. (You can find more testing commands in script.sh of each task directory)

cd tasks/csmri
python -W ignore main.py --solver admm --exp test -rs 15000 --max_episode_step 6 --action_pack 5 --eval -r ./checkpoints/csmri_admm_5x6_48/actor_0015000.pkl

cd tasks/pr
python main.py --solver iadmm --exp pr_admm_5x6_36 --eval --max_episode_step 6 --action_pack 5 -r ./checkpoints/pr_admm_5x6_36/actor_0015000.pkl -rs 15000

Training

1. Download the training data from Link, unzip and put it in tasks/[task]/data.
2. Run the following command to retrain the model. You need about 20G video memory for the training.

cd tasks/csmri
python -W ignore main.py --solver admm --exp csmri_admm_5x6_48_new --validate_interval 10 --env_batch 48 --rmsize 480 --warmup 20 -lp 0.05 --train_steps 15000 --max_episode_step 6 --action_pack 5 -le 0.2

cd tasks/pr
python main.py --solver iadmm --exp pr_admm_5x6_36 --validate_interval 50 --env_batch 36 --rmsize 360 --warmup 20 -lp 0.05 --train_steps 15000 --max_episode_step 6 --action_pack 5 -le 0.2
