SDF Classify

Content type classifier for the SDF Protocol. 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
