## 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**: 4x V100 GPU  
**Published**: Dec 8th, 2021

## Details
- haystack's distillation feature was used for training. deepset/roberta-large-squad2 was used as the teacher model.

## 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
