## DeBERTa: Decoding-enhanced BERT with Disentangled Attention |
|
|
|
[DeBERTa](https://arxiv.org/abs/2006.03654) improves the BERT and RoBERTa models using disentangled attention and enhanced mask decoder. With those two improvements, DeBERTa out perform RoBERTa on a majority of NLU tasks with 80GB training data. |
|
|
|
Please check the [official repository](https://github.com/microsoft/DeBERTa) for more details and updates. |
|
|
|
This is the DeBERTa V2 xxlarge model with 48 layers, 1536 hidden size. Total parameters 1.5B. It's trained with 160GB data. |
|
|
|
|
|
### Fine-tuning on NLU tasks |
|
|
|
We present the dev results on SQuAD 1.1/2.0 and several GLUE benchmark tasks. |

#### Notes. |
|
- <sup>1</sup> Following RoBERTa, for RTE, MRPC, STS-B, we fine-tune the tasks based on [DeBERTa-Large-MNLI](https://huggingface.co/microsoft/deberta-large-mnli), [DeBERTa-XLarge-MNLI](https://huggingface.co/microsoft/deberta-xlarge-mnli), [DeBERTa-V2-XLarge-MNLI](https://huggingface.co/microsoft/deberta-v2-xlarge-mnli), [DeBERTa-V2-XXLarge-MNLI](https://huggingface.co/microsoft/deberta-v2-xxlarge-mnli). The results of SST-2/QQP/QNLI/SQuADv2 will also be slightly improved when start from MNLI fine-tuned models, however, we only report the numbers fine-tuned from pretrained base models for those 4 tasks. |
|
- <sup>2</sup> To try the **XXLarge** model with **[HF transformers](https://huggingface.co/transformers/main_classes/trainer.html)**, you need to specify **--sharded_ddp** |
|
|
|
```bash |
|
cd transformers/examples/text-classification/ |
|
export TASK_NAME=mrpc |
|
python -m torch.distributed.launch --nproc_per_node=8 run_glue.py --model_name_or_path microsoft/deberta-v2-xxlarge \ |
|
--task_name $TASK_NAME --do_train --do_eval --max_seq_length 128 --per_device_train_batch_size 4 \ |
|
--learning_rate 3e-6 --num_train_epochs 3 --output_dir /tmp/$TASK_NAME/ --overwrite_output_dir --sharded_ddp --fp16 |
|
``` |
