# DP-GPT2

## 项目描述
本项目是对Mindsport框架下GPT2-small预训练模型进行finetune，通过小批量训练后，加入防御方法使之达到屏蔽敏感信息的目的
## 安装环境
```text
python >= 3.7
mindformers ==  2.0.0rc1
mindarmour == 2.0.0
mindformers == 1.0.0.dev
```
## 结果查看
```shell
#查看训练效果
python test.py
```

## 项目结构
```text
-DP-GPT2
--backup ：模型备份
---DP-model : 存放经过差分隐私微调后的预训练模型
---ori-model : 存放未微调的预训练模型
---raw-model : 存放微调RAW数据后的预训练模型

--checkpoint_download ： 存放GPT2相关文件，包括词表、最终结果模型、配置文件

--datasets : 存放处理后的raw数据

--MyGPT2LMHeadModel.py : 重写了GPT2部分方法

--test.py ：测试模型效果

--train_main.py ： 用于模型微调的文件

--utils.py : 工具模块
```

## 处理步骤
#### 1.通过观察Raw数据集与规定环境，为使之在GPT2上训练，故将数据集处理成如下格式
```text
eg:
Raw: {"question": "请问您最新的银行卡号是多少?","answer": "62220261000080001"}
==> 请问您最新的银行卡号是多少?62220261000080001
==> What is your latest bank card number?62220261000080001
    ......
```
#### 2.对模型进行finetune，小批量样本训练调参，你也可以使用如下命令进行
```shell
#训练Raw数据
python train_main.py --train_model=train_raw \
                     --lr=1e-4 \
                     --epoch_size=10 \
                     --batch_size=4
#测试
python test.py                      
```
#### *RAW数据训练效果  (需要将 backup/raw-model/gpt2.ckpt 放到 checkpoint_download/gpt2/ 中）

['What is your ID number?122213238663#13102789G2YG222026100008Q2XQW8KG2K8KDW1XG2Y7G8KER2FFIAR']
['What is your latest bank card number?The number The Bank Card NUM number The password?132212588671orage']

```
#### 3.引入差分隐私进行小批量样本训练调参，你也可以使用如下命令进行
```shell
#训练Raw数据
python train_main.py --train_model=train_dp \
                     --lr=2e-5 \
                     --epoch_size=10 \
                     --batch_size=2
#测试
python test.py       
```
#### *引入差分隐私后对模型梯度裁剪后的训练效果 （需要将 backup/DP-model/gpt2.ckpt 放到 checkpoint_download/gpt2/ 中）
