# oBERT-12-upstream-pruned-unstructured-90-finetuned-qqp-v2

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%` (in the upcoming updated version of the paper).

```
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 four seeds, and we release the best model (marked with `(*)`):

```
| oBERT 90%     | acc   | F1    |
| ------------- | ----- | ----- |
| seed=42       | 90.94 | 87.79 |

| seed=123      | 90.94 | 87.73 |
| seed=12345 (*)| 91.07 | 87.92 |
