模型信息 Model Information
问答在自然语言处理领域中反映AI系统的知识水平的重要任务。为了可以在医疗领域中使用强大的问答能力的语言模型，我们基于Yuyuan-GPT2-3.5B，对其使用了10K条医疗的问答对进行微调。我们希望探索一种简单、有效的方式直接实现问答系统而不需要额外的设计，即利用大模型强大的记忆力和理解能力。
Question answering (QA) is an important task in the Natural Language Processing to present the knowledge level of AI systems. To provide a language model with powerful QA capability in the medical domain, we fine-tuned Yuyuan-GPT2-3.5B on 10K medical Q&A pairs.
下游任务 Performance
我们测试了该模型在未见过的100条QA对上的表现：
We tested the model on 100 unseen QA pairs:
| gram | 1-gram | 2-gram | 3-gram | 4-gram |
|---|---|---|---|---|
| bleu score | 0.357727 | 0.2713 | 0.22304 | 0.19099 |
使用 Usage
加载模型 Loading Models
```python from transformers import GPT2Tokenizer,GPT2LMHeadModel
hfmodelpath = 'YuyuanQA-GPT2-3.5B'
tokenizer = GPT2Tokenizer.frompretrained(hfmodelpath) model = GPT2LMHeadModel.frompretrained(hfmodelpath)
### 使用示例 Usage Examples
python fquestion = "What should gout patients pay attention to in diet?" inputs = tokenizer(f'Question:{question} answer:',return_tensors='pt')
generationoutput = model.generate(**inputs, returndictingenerate=True, outputscores=True, maxlength=150, # maxnewtokens=80, dosample=True, topp = 0.6, eostokenid=50256, padtokenid=0, numreturnsequences = 5)
for idx,sentence in enumerate(generation_output.sequences): print('next sentence %d:\n'%idx, tokenizer.decode(sentence).split('<|endoftext|>')[0]) print(''40)
### 演示 Demo
我们用该模型做了一个医疗问答演示。
We made a demo of medical QA system with this model.
