From the Hugging Face model README
This model performs Handwritten Text Recognition in Norwegian. It was developed during the HUGIN-MUNIN project.
The model was trained using the PyLaia library on the NorHand v2 dataset.
Training images were resized with a fixed height of 128 pixels, keeping the original aspect ratio.
| set | lines | horizontal lines |
|---|---|---|
| train | 146,693 | 145,061 |
| val | 15,119 | 14,980 |
| test | 1,830 | 1,793 |
An external 6-gram character language model can be used to improve recognition. The language model is trained on the text from the NorHand v2 training set.
The model achieves the following results:
| set | Language model | CER (%) | WER (%) | lines |
|---|---|---|---|---|
| test | no | 3.82 | 12.00 | 1,573 |
| test | yes | 3.13 | 9.29 | 1,573 |
Please refer to the PyLaia documentation to use this model.
