## Details
|
| 22 |
+
- We trained a German question answering model with a gelectra-base model as its basis.
|
| 23 |
+
- The dataset is GermanQuAD, a new, German language dataset, which we hand-annotated and published [online](https://deepset.ai/germanquad).
|
| 24 |
+
- 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.
|
| 25 |
+
- 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.
|
| 26 |
+
|
| 27 |
+
See https://deepset.ai/germanquad for more details and dataset download in SQuAD format.

## Hyperparameters
|
| 30 |
+
```
|
| 31 |
+
batch_size = 80
|
| 32 |
+
n_epochs = 4
|
| 33 |

max_seq_len = 384
|
| 34 |
+
learning_rate = 3e-5
|
| 35 |

## Performance
|
| 41 |
+
We evaluated the extractive question answering performance on the SQuAD v2 dev set.
|
| 42 |
+
Model types and training data are included in the model name.
|
| 43 |
+
For finetuning XLM-Roberta, we use the English SQuAD v2.0 dataset.
|
| 44 |
+
The GELECTRA models are warm started on the German translation of SQuAD v1.1 and finetuned on \\\\germanquad.
|
| 45 |
+
The human baseline was computed for the 3-way test set by taking one answer as prediction and the other two as ground truth.
