| # SDF Classify |
|
|
| Content type classifier for the [SDF Protocol](https://sdfprotocol.org). Fine-tuned from Qwen2.5-1.5B-Instruct using QLoRA. |
|
|
| ## Purpose |
|
|
| Classifies web content into SDF's hierarchical type system: 10 parent types and 50+ subtypes (e.g., `article.news`, `commerce.product`, `documentation.api_docs`). |
|
|
| ## Training |
|
|
| - **Base model**: Qwen2.5-1.5B-Instruct |
| - **Method**: QLoRA (rank 32, alpha 64, dropout 0.05) |
| - **Training data**: 2,335 classified web documents |
| - **Accuracy**: 95.2% exact type match |
