## Overview
**Language model:** deepset/roberta-base-squad2-distilled   
**Language:** German  
**Training data:** GermanQuAD train set (~ 12MB)  
**Eval data:** GermanQuAD test set (~ 5MB)   
**Infrastructure**: 1x V100 GPU  
**Published**: Apr 21st, 2021

## Details
- We trained a German question answering model with a gelectra-base model as its basis.
- The dataset is GermanQuAD, a new, German language dataset, which we hand-annotated and published [online](https://deepset.ai/germanquad).
- The training dataset is one-way annotated and contains 11518 questions and 11518 answers, while the test dataset is three-way annotated so that there are 2204 questions and with 2204·3−76 = 6536answers, because we removed 76 wrong answers.
- In addition to the annotations in GermanQuAD, haystack's distillation feature was used for training. deepset/roberta-large-squad2 was used as the teacher model.

See https://deepset.ai/germanquad for more details and dataset download in SQuAD format.

## Hyperparameters
```
batch_size = 80
n_epochs = 4
max_seq_len = 384
learning_rate = 3e-5
lr_schedule = LinearWarmup
embeds_dropout_prob = 0.1
temperature = 1.5
distillation_loss_weight = 0.75
```
## Performance
We evaluated the extractive question answering performance on the SQuAD v2 dev set.
Model types and training data are included in the model name. 
For finetuning XLM-Roberta, we use the English SQuAD v2.0 dataset.
The GELECTRA models are warm started on the German translation of SQuAD v1.1 and finetuned on \\\\germanquad. 
The human baseline was computed for the 3-way test set by taking one answer as prediction and the other two as ground truth.
