# Handwriting orientation runtime assets

`model.joblib` contains the trained RBF SVM and ExtraTrees fusion head.
Training assessments: Interro01, 02, 03, 05. Calibration: Interro06.
The conservative operating threshold is 0.3044920634920634.

`doc.onnx` is PaddlePaddle's PP-LCNet_x1_0_doc_ori, Apache-2.0:
https://huggingface.co/PaddlePaddle/PP-LCNet_x1_0_doc_ori_onnx

`settings.json` retains thresholds, model hashes and validation provenance.
Do not replace weights without matching preprocessing and recalibration.
The runtime uses scikit-learn 1.9.1 and ONNX Runtime 1.31.1.

See docs/page_orientation.md and docs/orientation_final_training.md for the
algorithm, experiments, evidence and limitations.
