HF-version model for PRIMERA: Pyramid-based Masked Sentence Pre-training for Multi-document Summarization (ACL 2022).

The original code can be found here . You can find the script and notebook to train/evaluate the model in the original github repo.

• Note: due to the difference between the implementations of the original Longformer and the Huggingface LED model, the results of converted models are slightly different. We run a sanity check on both fine-tuned and non fine-tuned models on the MultiNews dataset, and show the results below:

| Model | Rouge-1 | Rouge-2 | Rouge-L |

| --- | ----------- |----------- |----------- |

| PRIMERA | 42.0 | 13.6 | 20.8|

| PRIMERA-hf | 41.7 |13.6 | 20.5|

| PRIMERA(finetuned) | 49.9 | 21.1 | 25.9|

| PRIMERA-hf(finetuned) | 49.9 | 20.9 | 25.8|

You can use it by

from transformers import (

    AutoTokenizer,

    LEDConfig,

    LEDForConditionalGeneration,

)

tokenizer = AutoTokenizer.from_pretrained('allenai/PRIMERA')

config=LEDConfig.from_pretrained('allenai/PRIMERA')

model = LEDForConditionalGeneration.from_pretrained('allenai/PRIMERA')

PRIMERA的HF版本模型：基于金字塔的用于多文档摘要的掩码句子预训练（ACL 2022）。

原始代码可在 here 处找到。您可以在原始的github存储库中找到用于训练/评估模型的脚本和笔记本。

• 注意：由于原始Longformer和Huggingface LED模型之间实现的差异，转换模型的结果略有不同。我们在MultiNews数据集上对细调和非细调模型进行了合理性检查，并在下面显示了结果：

| 模型 | Rouge-1 | Rouge-2 | Rouge-L |

| --- | ----------- |----------- |----------- |

| PRIMERA | 42.0 | 13.6 | 20.8|

| PRIMERA-hf | 41.7 |13.6 | 20.5|

| PRIMERA（细调） | 49.9 | 21.1 | 25.9|

| PRIMERA-hf（细调） | 49.9 | 20.9 | 25.8|

您可以通过

from transformers import (

    AutoTokenizer,

    LEDConfig,

    LEDForConditionalGeneration,

)

tokenizer = AutoTokenizer.from_pretrained('allenai/PRIMERA')

config=LEDConfig.from_pretrained('allenai/PRIMERA')

model = LEDForConditionalGeneration.from_pretrained('allenai/PRIMERA')
