transformer's Introduction

Transformer pytorch实现

笔记

setting.py:模型相关参数,文件目录的配置文件。
utils.py:一些工具函数,比如不等长句子的padding等等。
data_pre.py:数据的预处理,得到输出模型的batch数据和相关的mask矩阵
model.py:模型文件。通过调用make_model方法传入相关模型初始化参数,来对模型进行初始化。
train.py:进行模型的训练。和最好模型的保存。
test.py:对测试集句子的测试输出。
bleu_score.py:对机器翻译评分。
one_trans.py:实现单个句子进行翻译。
app.py:通过使用one_trans文件封装的单个句子翻译的方法,实现flask api

flask api请求参数

简单api,没有进行检查校验和异常处理

// POST请求参数
{
  "sentence": "your  translation sentences"
}
// return
{
  "result": "翻译结果",
  "msg": 'success',
  "code": 200
}

模型训练数据

使用14533条翻译数据进行训练。
数据文件格式:en\tcn

结果评估

使用BLEU算法进行翻译效果评估BLEU BLEU算法评价结果:

对399条翻译句子效果进行评估
验证集:0.1075088492716548,n-gram权重:(1,0,0,0)
      0.03417978514554449,n-gram权重:(1,0.2,0,0)

Attention:运行代码之前需要自己在项目目录下新建一个save文件夹

Transformer讲解

运行项目

  1. python train.py:训练模型,保存模型
  2. python app.py启动服务。

python test.py,测试模型的测试集上的效果(这里用的是验证集)
