It works best on dense educational pages with clear question boundaries. ## Release notes This release checkpoint is a cleaned fine-tune of a previously trained YOLO26M run, finalized without mosaic augmentation. ## Test results ### Old held-out test set | Model | Precision | Recall | mAP50 | mAP50-95 | | --- | --- | --- | --- | --- | | YOLO26M Question Segmentation | 0.990 | 0.982 | 0.988 | 0.920 | ### Combined held-out test set | Model | Precision | Recall | mAP50 | mAP50-95 | | --- | --- | --- | --- | --- | | YOLO26M Question Segmentation | 0.987 | 0.978 | 0.992 | 0.957 | ## Usage ```python from ultralytics import YOLO model = YOLO("hf://samil24/yolo26m-question-segmentation") results = model("page.png", imgsz=1280, conf=0.25) ``` ## Included files - `best.pt`: release checkpoint - `metrics_summary.json`: test-set metrics for this release - `confidence_sweep_summary.json`: confidence sweep outputs used during evaluation - `comparison_examples/`: side-by-side qualitative examples ## Data note Some of the training data comes from public Roboflow projects used in earlier versions of this question-segmentation pipeline: 1. **PDF Soru Cikarma** (tanimazsinu): [Link](https://universe.roboflow.com/tanimazsinu/pdf-soru-cikarma-wmwfu) 2. **WholeQuestionDetection** (Gazi University): [Link](https://universe.roboflow.com/gazi-university-gi7lx/wholequestiondetection) 3. **ExamBuddy** (ExamBuddy): [Link](https://universe.roboflow.com/exambuddy/exambuddy) 4. **Questions** (Terry Li): [Link](https://universe.roboflow.com/terry-li/questions-klidd) 5. **Question Parsing from Document** (Sefa): [Link](https://universe.roboflow.com/sefa-8tkmm/question-parsing-from-document) 6. **Question Dedector** (Nur Etinkaya): [Link](https://universe.roboflow.com/nur-etinkaya/question-dedector) 7. **Sorukes** (Sorualgilama...
