## Model Description
This model extracts structured Z-number decision matrices from conversational text describing multi-criteria decision problems. Given a natural language narrative about alternatives, criteria, and preferences (often messy, subjective, or contradictory), the model outputs a markdown table with:
- **Alternatives** (e.g., train, flight, driving)
- **Criteria** (e.g., cost, comfort, reliability)
- **Z-number ratings** in `value:confidence` format (e.g., `4:3` = good rating with moderate confidence)
Z-numbers extend traditional fuzzy numbers by incorporating reliability/confidence, making them ideal for real-world decision-making under uncertainty.
## Intended Use
The extracted matrix can be analyzed using Z-number-based MCDM methods (TOPSIS, PROMETHEE) to produce ranked alternatives. See [text2mcdm](https://github.com/MahammadNuriyev62/text2mcdm) for the full pipeline.
## Training
- **Base model**: Qwen/Qwen3-4B-Instruct-2507
- **Method**: LoRA fine-tuning with Unsloth
- **Data**: [nuriyev/text2mcdm](https://huggingface.co/datasets/nuriyev/text2mcdm) (~600 synthetic decision narratives generated via Gemini API)
