# PyLaia - Fraktur

This model performs Handwritten Text Recognition in Austrian German. 

## Model description

The model has been trained using the PyLaia library on the [NewsEye / READ OCR training dataset from Austrian Newspapers (19th C.)](https://zenodo.org/record/3387369) dataset.

Training images were resized with a fixed height of 128 pixels, keeping the original aspect ratio.

| split | N lines |
| ----- | ------: |
| train |  52,834 |
| val   |   4,667 |

An external 6-gram character language model can be used to improve recognition. The language model is trained on the text from the NewsEye training set.

## Evaluation results

The model achieves the following results:

| set   | Language model | CER (%)    | WER (%) | N lines   |
|:------|:---------------|:----------:|:-------:|----------:|
| val   | no             | 1.82       |   7.77  |     4,667 |
| val   | yes            |  1.77      |   7.01  |     4,667 |
