# Fine-tuned Flair Model on Dutch ICDAR-Europeana NER Dataset

This Flair model was fine-tuned on the
[Dutch ICDAR-Europeana](https://github.com/stefan-it/historic-domain-adaptation-icdar)
NER Dataset using hmBERT as backbone LM.

The ICDAR-Europeana NER Dataset is a preprocessed variant of the
[Europeana NER Corpora](https://github.com/EuropeanaNewspapers/ner-corpora) for Dutch and French.

The following NEs were annotated: `PER`, `LOC` and `ORG`.

# Results

We performed a hyper-parameter search over the following parameters with 5 different seeds per configuration:

* Batch Sizes: `[8, 4]`
* Learning Rates: `[3e-05, 5e-05]`

And report micro F1-score on development set:

| Configuration   | Run 1        | Run 2        | Run 3        | Run 4        | Run 5        | Avg.         |
|-----------------|--------------|--------------|--------------|--------------|--------------|--------------|
| bs8-e10-lr5e-05 | [0.8191][1]  | [0.8086][2]  | [0.8237][3]  | [0.8318][4]  | [0.8235][5]  | 82.13 ± 0.76 |
| bs8-e10-lr3e-05 | [0.8056][6]  | [0.8183][7]  | [0.8241][8]  | [0.8431][9]  | [0.8155][10] | 82.13 ± 1.24 |
| bs4-e10-lr5e-05 | [0.8055][11] | [0.822][12]  | [0.8243][13] | [0.8093][14] | [0.8144][15] | 81.51 ± 0.72 |
| bs4-e10-lr3e-05 | [0.8039][16] | [0.8122][17] | [0.8073][18] | [0.8246][19] | [0.8132][20] | 81.22 ± 0.7  |

The [training log](training.log) and TensorBoard logs (only for hmByT5 and hmTEAMS based models) are also uploaded to the model hub.
