# Pylia - Esposalles handwritten text recognition
This model performs Handwritten Text Recognition in Catalan (19th century).
## Model description
The model has been trained using the PyLaia library on the [Esposalles](https://rrc.cvc.uab.es/?ch=10&com=introduction/) dataset.
Training images were resized with a fixed height of 128 pixels, keeping the original aspect ratio.
| split | N lines |
| ----- | ------: |
| train | 2,328 |
| val | 742 |
| test | 757 |
An external 6-gram character language model can be used to improve recognition. The language model is trained on the text from the Esposalles training set.
## Evaluation results
The model achieves the following results:
| set | Language model | CER (%) | WER (%) | N lines |
|:------|:---------------|:----------:|:-------:|----------:|
| test | no | 0.76 | 2.62 | 757 |
| test | yes | 1.04 | 3.38 | 757 |
