| # RL-Struct: Bridging the Structure Gap | |
| [ไธญๆ็ๆฌ](./README_CN.md) | [๐ Paper](https://huggingface.co/papers/2512.00319) | |
| We introduce **RL-Struct**, a lightweight Reinforcement Learning framework designed to solve the "Structure Gap"โthe tension between probabilistic token generation and deterministic structured formats (e.g., JSON). By leveraging **GRPO (Gradient Regularized Policy Optimization)** and a **Multi-dimensional Reward Function**, our model achieves superior structural reliability without the high inference latency of constrained decoding. | |
| ## ๐ Key Features | |
| - **Multi-dimensional Reward Function**: Decomposes the objective into Structure, Format, Validity, Correctness, and Length. | |
| - **Efficient Training**: Uses GRPO to eliminate the critic network, reducing VRAM usage by ~40% compared to PPO. | |
| - **Emergent Curriculum**: The model spontaneously learns syntax (how to speak) before semantics (what to say). | |
| - **High Performance**: Achieves **89.7% Structural Accuracy** and **92.1% JSON Validity** on complex recipe generation, outperforming LLaMA-3-8B and GPT-3.5. | |
| ## ๐ Model Details | |
| - **Base Model:** [Qwen/Qwen3-4B-Instruct-2507](https://huggingface.co/Qwen/Qwen3-4B-Instruct-2507) | |
| - **Training Method:** GRPO (Reinforcement Learning) + LoRA | |
| - **Task:** Structured Output Generation (JSON Recipes, GSM8K-JSON, ToolUse) | |
| - **License:** Apache-2.0 | |
| ## ๐ ๏ธ Usage | |
| The following is the system prompt: | |
| ```text | |
| You are a precise recipe assistant. Always respond in the following JSON format: | |
| { | |
| "reasoning": "Your step-by-step reasoning here...", | |
| "answer": "{\"name\": \"Recipe Name\", \"nutrition\": \"Calories: ..., Protein: ..., Fat: ...\"}" | |
| } | |
| Do not include any other text, explanations, or markdown. Only output valid JSON. | |
| ``` | |
| ## ๐ Performance | |
| | Method | Structural Acc. | JSON Validity | Content Acc. | | |
| | :--- | :---: | :---: | :---: | | |
| | GPT-3.5 (Zero-shot) | 45.5% | 82.1% | 88.0% | | |
| | LLaMA-3-8B (SFT) | 78.2% | 85.4% | 86.0% | | |
| | **RL-Struct (Ours)** | **89.7%** | **92.1%** | **84.5%** | |
