+# 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 hmByT5 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`.
+
+# ⚠️ Inference Widget ⚠️
+
+Fine-Tuning ByT5 models in Flair is currently done by implementing an own [`ByT5Embedding`][1] class.
+
+This class needs to be present when running the model with Flair.
+
+Thus, the inference widget is not working with hmByT5 at the moment on the Model Hub and is currently disabled.
+
+This should be fixed in future, when ByT5 fine-tuning is supported in Flair directly.

+
+# Results
+
+We performed a hyper-parameter search over the following parameters with 5 different seeds per configuration:
+
+* Batch Sizes: `[8, 4]`
+* Learning Rates: `[0.00015, 0.00016]`
+
+And report micro F1-score on development set:
+
+| Configuration     | Run 1        | Run 2        | Run 3        | Run 4        | Run 5        | Avg.         |
