Replicate Package — Privacy‑Preserving Compressive Sensing Reconstruction

This repository provides a minimal, reproducible evaluation package for the corresponding research paper.
It includes pretrained checkpoints, evaluation scripts, and robustness/attack evaluation code so that reviewers and readers can reproduce the main results without retraining models.

2. Environment Setup

conda create -n privcs python=3.9 -y
conda activate privcs
pip install -r requirements.txt

---

3. Execution Convention

Always run scripts from the repository root using module mode:

python -m scripts.eval_reconstruction

---

4. Normal Reconstruction Evaluation

python -m scripts.eval_reconstruction \
  --dataset cifar10 \
  --ckpt_root checkpoints/ckpt_recon \
  --compression_rates 30 \
  --epsilons 1 \
  --batch_size 256

---

5. Reconstruction Attack Evaluation

python -m scripts.eval_attack_recon \
  --dataset cifar10 \
  --ckpt_root checkpoints \
  --compression_rates 30 \
  --batch_size 256

---

6. FGSM Attack Evaluation

python -m scripts.eval_attack_fgsm \
  --dataset cifar10 \
  --ckpt_root checkpoints/ckpt_recon \
  --compression_rates 30 \
  --epsilon 1 \
  --adv_scale 0.1

---

7. Gaussian Noise Robustness Evaluation

python -m scripts.eval_robust_gaussian \
  --dataset cifar10 \
  --ckpt_root checkpoints/ckpt_recon \
  --compression_rates 30 \
  --epsilon 1 \
  --gaussian_scale 0.20

---

8. Metrics

• PSNR / SSIM
• SSIM uses win_size = 3 for CIFAR‑10

---

9. Checkpoints Policy

Only selected checkpoints are uploaded to ensure reproducibility while keeping the repository lightweight.
