# PyLaia - RIMES

This model performs Handwritten Text Recognition in French.

## Model description

The model has been trained using the PyLaia library on the [RIMES](https://teklia.com/research/rimes-database/) dataset.

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

| set   | lines   | 
|:----- | ------: | 
| train | 10,188  |
| val   |  1,138  |
| test  |    778  |

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

## Evaluation results

The model achieves the following results:

| set   | Language model | CER (%)    | WER (%) | lines   |
|:------|:---------------| ----------:| -------:|--------:|
| test  | no             | 4.53       | 15.06   |    778  |
| test  | yes            | 3.47       | 10.20   |    778  |

## How to use?
