# Jobs job-category classifier (sklearn)

This repo holds the trained artifact consumed by **jobs-shared**
|
| 13 |
+
(`jobs_shared.ai.categorizers.pipeline`) for the findjobs taxonomy.
|
| 14 |
|
| 15 |
+
- **Weights:** `category.joblib` — `joblib`-serialized scikit-learn `Pipeline`
|
| 16 |
+
(`TfidfVectorizer` + `LogisticRegression`), plus artifact keys `fields`
|
| 17 |
+
and `input_joiner`. Compressed with `joblib.dump(..., compress=3)`.
|
| 18 |

- **Upstream:** Produced by ``scripts/train/train_category.py``.
