## 🌟 Highlights & Model Specs
|
| 28 |
+
|
| 29 |
+
- **Attention-Adaptive Feed-Forward Network (AA-FFN)**: Dynamically refines feature representation while drastically cutting down computational overhead.
|
| 30 |
+
- **Ultra Lightweight & Fast**: Only **0.866 M** parameters and **7.36 G MACs** (evaluated on 256×256 input size).
|
| 31 |
+
- **State-of-the-Art Performance**: Achieves **38.21 dB PSNR** on SOTS-Indoor and **39.61 dB PSNR** on RS-Haze.
