# hmByT5 - Preliminary Language Models
Preliminary Historic Multilingual and Monolingual ByT5 Models. Following languages are currently covered:
* Dutch (Delpher Corpus)
More details can be found in [our GitHub repository](https://github.com/stefan-it/hmByT5).
# Pretraining
We use the official JAX/FLAX example in Hugging Face Transformers to pretrain a ByT5 model on a single v3-8 TPU.
Details about the training can be found [here](https://github.com/stefan-it/hmByT5/tree/main/hmbyt5-flax).
This model was trained with `mean_noise_span_length=20`.
# Evaluation on Downstream Tasks (NER)
We evaluated the hmByT5 model on ICDAR Europeana dataset:
| Configuration | Run 1 | Run 2 | Run 3 | Run 4 | Run 5 | Avg. |
|------------------------------------------|-------|-------|-------|-------|-------|--------------|
| `wsFalse-bs4-e10-lr0.00015-poolingfirst` | 86.61 | 85.88 | 87.65 | 87.93 | 88.01 | 87.22 ± 0.83 |
| `wsFalse-bs8-e10-lr0.00015-poolingfirst` | 87.88 | 87.56 | 85.62 | 86.52 | 87.03 | 86.92 ± 0.8 |
| `wsFalse-bs4-e10-lr0.00016-poolingfirst` | 86.17 | 85.87 | 87.77 | 86.58 | 87.96 | 86.87 ± 0.85 |
| `wsFalse-bs8-e10-lr0.00016-poolingfirst` | 87.67 | 86.02 | 85.66 | 87 | 85.99 | 86.47 ± 0.75 |
The results show no performance improvement of the [model](https://huggingface.co/hmbyt5/byt5-small-historic-dutch)
trained with `mean_noise_span_length=3`, that achieved 87.90 ± 0.71.
