	## 简介 Brief Introduction

	善于处理NLU任务，使用了N-gram编码增强文本语义，2.24亿参数量的ZEN1

	ZEN1 model, which uses N-gram to enhance text semantic and has 224M parameters, is adept at NLU tasks.

	## 模型分类 Model Taxonomy

	\| 需求 Demand \| 任务 Task \| 系列 Series \| 模型 Model \| 参数 Parameter \| 额外 Extra \|

	\| 通用 General \| 自然语言理解 NLU \| 二郎神 Erlangshen \| ZEN1 \| 224M \| 中文-Chinese \|

	## 模型信息 Model Information

	我们与[ZEN团队](https://github.com/sinovation/ZEN)合作，使用我们的封神框架，开源发布了ZEN1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。ZEN1可以通过仅在单个小语料库(低资源场景)上进行训练来获得良好的性能增益。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 ZEN1 using our Fengshen Framework in collaboration with the [ZEN team](https://github.com/sinovation/ZEN). More precisely, by bringing together knowledge extracted by unsupervised learning, ZEN learns different textual granularity information through N-gram methods. ZEN1 can obtain good performance gains by training only on a single small corpus (low-resource scenarios). 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](https://github.com/huggingface/transformers)库中是没有ZEN1相关的模型结构的，所以你可以在我们的[Fengshenbang-LM](https://github.com/IDEA-CCNL/Fengshenbang-LM)中找到并且运行代码。

	Since there is no structure of ZEN1 in [transformers library](https://github.com/huggingface/transformers), you can find the structure of ZEN1 and run the codes in [Fengshenbang-LM](https://github.com/IDEA-CCNL/Fengshenbang-LM).

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

	```python
	from fengshen.models.zen1.ngram_utils import ZenNgramDict
	from fengshen.models.zen1.tokenization import BertTokenizer
	from fengshen.models.zen1.modeling import ZenForSequenceClassification, ZenForTokenClassification

	pretrain_path = 'IDEA-CCNL/Erlangshen-ZEN1-224M-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)

	```
