我们与ZEN团队合作，使用我们的封神框架，开源发布了ZEN2模型。具体而言，通过引入无监督学习中提取的知识，ZEN通过N-gram方法学习不同的文本粒度信息。ZEN2使用大规模数据集和特殊的预训练策略对N-gram增强编码器进行预训练。下一步，我们将继续与ZEN团队一起探索PLM的优化，并提高下游任务的性能。

We open source and publicly release ZEN2 using our Fengshen Framework in collaboration with the ZEN team. More precisely, by bringing together knowledge extracted by unsupervised learning, ZEN learns different textual granularity information through N-gram methods. ZEN2 pre-trains the N-gram-enhanced encoders with large-scale datasets and special pre-training strategies. In the next step, we continue with the ZEN team to explore the optimization of PLM and improve the performance on downstream tasks.

使用 Usage

因为transformers库中是没有ZEN2相关的模型结构的，所以你可以在我们的Fengshenbang-LM中找到并且运行代码。

Since there is no structure of ZEN2 in transformers library, you can find the structure of ZEN2 and run the codes in Fengshenbang-LM.

git clone https://github.com/IDEA-CCNL/Fengshenbang-LM.git

python

from fengshen.models.zen2.ngram_utils import ZenNgramDict
from fengshen.models.zen2.tokenization import BertTokenizer
from fengshen.models.zen2.modeling import ZenForSequenceClassification, ZenForTokenClassification

pretrain_path = 'IDEA-CCNL/Erlangshen-ZEN2-668M-Chinese'

tokenizer = BertTokenizer.from_pretrained(pretrain_path)
model_classification = ZenForSequenceClassification.from_pretrained(pretrain_path)
model_extraction = ZenForTokenClassification.from_pretrained(pretrain_path)
ngram_dict = ZenNgramDict.from_pretrained(pretrain_path, tokenizer=tokenizer)
