Fine-tuned Flair Model on Swedish NewsEye NER Dataset (HIPE-2022)

This Flair model was fine-tuned on the Swedish NewsEye 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.

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 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:

And report micro F1-score on development set:

Configuration Run 1 Run 2 Run 3 Run 4 Run 5 Avg.
bs4-e10-lr0.00016 0.8015 0.7653 0.7776 0.8096 0.7963 79.01 ± 1.62

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