German FinBERT is a BERT language model focusing on the financial domain within the German language. In my
paper, I describe in more detail the steps taken to train the model and show that it outperforms its generic benchmarks for finance specific downstream tasks.

I fine-tune the model using the 1cycle policy of
Smith and Topin (2019). I use the Adam optimization method of
Kingma and Ba (2014) with
standard parameters.I run a grid search on the evaluation set to find the best hyper-parameter setup. I test different
values for learning rate, batch size and number of epochs, following the suggestions of
Chalkidis et al. (2020). I repeat the fine-tuning for each setup five times with different seeds, to avoid getting good results by chance.
After finding the best model w.r.t the evaluation set, I report the mean result across seeds for that model on the test set.
For additional details regarding the performance on fine-tune datasets and benchmark results, please refer to the full documentation provided in the study.
