# oBERT-12-upstream-pruned-unstructured-90-finetuned-qqp

This model is obtained with [The Optimal BERT Surgeon: Scalable and Accurate Second-Order Pruning for Large Language Models](https://arxiv.org/abs/2203.07259).


It corresponds to the model presented in the `Table 2 - oBERT - QQP 90%`.

```
Pruning method: oBERT upstream unstructured + sparse-transfer to downstream
Paper: https://arxiv.org/abs/2203.07259
Dataset: QQP
Sparsity: 90%
Number of layers: 12
```

The dev-set performance reported in the paper is averaged over three seeds, and we release the best model (marked with `(*)`):

```
| oBERT 90%    | acc   | F1    |
| ------------ | ----- | ----- |
| seed=42   (*)| 90.93 | 87.77 |
| seed=3407    | 90.70 | 87.49 |
| seed=54321   | 90.86 | 87.68 |
| ------------ | ----- | ----- |
| mean         | 90.83 | 87.65 |
| stdev        | 0.117 | 0.143 |
