German BERT large paraphrase euclidean

This is a sentence-transformers model. It maps sentences & paragraphs (text) into a 1024 dimensional dense vector space. The model is intended to be used together with SetFit to improve German few-shot text classification. It has a sibling model called deutsche-telekom/gbert-large-paraphrase-cosine.

This model is based on deepset/gbert-large. Many thanks to deepset!


Loss Function
We have used BatchHardSoftMarginTripletLoss with eucledian distance as the loss function:

    train_loss = losses.BatchHardSoftMarginTripletLoss(

Training Data
The model is trained on a carefully filtered dataset of deutsche-telekom/ger-backtrans-paraphrase. We deleted the following pairs of sentences:

  • min_char_len less than 15
  • jaccard_similarity greater than 0.3
  • de_token_count greater than 30
  • en_de_token_count greater than 30
  • cos_sim less than 0.85


  • learning_rate: 5.5512022294147105e-06
  • num_epochs: 7
  • train_batch_size: 68
  • num_gpu: ???

Evaluation Results

We use the NLU Few-shot Benchmark - English and German dataset to evaluate this model in a German few-shot scenario.
