# DGA SGD Detector

This model was trained on the `asobirov/dga-preprocessed` dataset using:
- **HashingVectorizer** (char 2–5 grams, 2**20 hash buckets)
- **SGDClassifier** with online `partial_fit` and incremental learning-rate tuning
- Lightweight stats: length, digit ratio, Shannon entropy
- **Streaming training** on ~5 M domains, evaluated on ~1 M test domains from [harpomaxx/dga-detection](https://huggingface.co/harpomaxx/dga-detection) and [YangYang-Research/dga-detection](https://huggingface.co/YangYang-Research/dga-detection)
- **Decision threshold** optimized for F1 (=0.0794) yielding 85.7% accuracy, 83.6% DGA recall
