+# Fine-tuned Flair Model on French NewsEye NER Dataset (HIPE-2022)
+
+This Flair model was fine-tuned on the
+[French NewsEye](https://github.com/hipe-eval/HIPE-2022-data/blob/main/documentation/README-newseye.md)
+NER Dataset using hmByT5 as backbone LM.
+
+The NewsEye dataset is comprised of diachronic historical newspaper material published between 1850 and 1950
+in French, German, Finnish, and Swedish.
+More information can be found [here](https://dl.acm.org/doi/abs/10.1145/3404835.3463255).
+
+The following NEs were annotated: `PER`, `LOC`, `ORG` and `HumanProd`.
+
+# ⚠️ 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.         |
