## Overview
**Language model:** deepset/roberta-base-squad2-distilled   
**Language:** English  
**Training data:** SQuAD 2.0 training set  
**Eval data:** SQuAD 2.0 dev set  
**Infrastructure**: 1x V100 GPU   
**Published**: Apr 21st, 2021 

## Details
- haystack's distillation feature was used for training. deepset/bert-large-uncased-whole-word-masking-squad2 was used as the teacher model.

## Hyperparameters
```
batch_size = 6
n_epochs = 2
max_seq_len = 384
learning_rate = 3e-5
lr_schedule = LinearWarmup
embeds_dropout_prob = 0.1
temperature = 5
distillation_loss_weight = 1
```
## Performance
```
"exact": 68.6431398972458
