# REACT++ Scene Graph Generation — VG150 (yolo12m, yolo26m, yolov8m)
This repository contains **REACT++** model checkpoints for scene graph generation (SGG)
on the **VG150** benchmark, across 3 backbone sizes.
REACT++ is a parameter-efficient, attention-augmented relation predictor built on top of
a YOLO backbone. It uses:
- **DAMP** (Detection-Anchored Multi-Scale Pooling), a new simple pooling algorithm for one-stage object detectors such as YOLO
- **SwiGLU gated MLP** for all feed-forward blocks (½ the params of ReLU-MLP at equal capacity)
- **Visual x Semantic cross-attention** — visual tokens attend to GloVe prototype embeddings
- **Geometry RoPE** — box-position encoded as a rotary frequency bias on the Q matrix
- **Prototype Momentum Buffer** — per-class EMA prototype bank
- **P5 Scene Context** — AIFI-enhanced P5 tokens provide global context via cross-attention
The models were trained with the
[SGG-Benchmark](https://github.com/Maelic/SGG-Benchmark) framework and described in the
[REACT++ paper (Neau et al., 2026)](https://arxiv.org/abs/2603.06386).

## Usage
### ONNX (recommended — no Python dependencies beyond onnxruntime)
```python
from huggingface_hub import hf_hub_download
onnx_path = hf_hub_download(
repo_id="maelic/REACT-pp-VG150",
filename="yolo12m/react_pp_yolo12m.onnx",
repo_type="model",
)
# Run with tools/eval_onnx_psg.py or load directly via onnxruntime
```
### PyTorch
```python
# 1. Clone the repository
# git clone https://github.com/Maelic/SGG-Benchmark
# 2. Install dependencies
# pip install -e .
# 3. Download checkpoint + config
from huggingface_hub import hf_hub_download
ckpt_path = hf_hub_download(
repo_id="maelic/REACT-pp-VG150",
filename="yolo12m/best_model.pth",
repo_type="model",
)
cfg_path = hf_hub_download(
repo_id="maelic/REACT-pp-VG150",
filename="yolo12m/config.yml",
repo_type="model",
)
# 4. Run evaluation
import subprocess
subprocess.run([
"python", "tools/relation_eval_hydra.py",
"--config-path", str(cfg_path),
"--task", "sgdet",
"--eval-only",
"--checkpoint", str(ckpt_path),
])
```
