# AffHandGen — Affordance-Guided Diffusion Priors
Diffusion prior checkpoints for **"Affordance-Guided Diffusion Prior for 3D Hand
Reconstruction"** (arXiv:2510.00506).
The priors generate MANO hand poses conditioned on affordance text descriptions
(DistilBERT) and image features (HaMeR ViT), and are used for test-time
refinement of 3D hand reconstructions under occlusion.
| File | Trained on | Used for |
|---|---|---|
| `hog/ckpt_best.pth` | HOGraspNet (S1 train) | Table 1 HOGraspNet rows |
| `ho3d/ckpt_best.pth` | HO3D | Table 1 HO3D rows |
Each directory also contains the exact `train.yml` used for training.
## Usage
See the [code repository](https://github.com/narudesuyo/AffHandGen) —
`docs/REPRODUCING.md` describes the full reproduction procedure. Place the
checkpoints at:
```
output/exp/hog/uniaff_cond_20260228_v1/ckpt_best.pth
output/exp/ho3d/20260227_v1/ckpt_best.pth
```
