chinese-text-classification-mindspore's Introduction

Chinese-Text-Classification-Mindspore

中文文本分类,TextCNN,TextRNN,FastText,TextRCNN,BiLSTM_Attention, DPCNN, Transformer, 基于mindspore,开箱即用。

介绍

声明:

本项目是通过原Chinese-Text-Classification-Pytorch项目针对pytorch进行mindspore框架的模型迁移与训练,旨在让更多感兴趣的人能够上手mindspore并了解、支持mindspore的研发,做出贡献加速mindspore社区成长与完善,欢迎star:star2::blush::two_hearts:

Mindspore:

昇思MindSpore通过社区合作,面向全场景构建最佳昇腾匹配、支持多处理器架构的开放AI架构,为算法工程师和数据科学家提供开发友好、运行高效、部署灵活的体验,帮助人工智能软硬件应用生态繁荣发展。

数据以字为单位输入模型,预训练词向量使用 搜狗新闻 Word+Character 300d点这里下载

环境

python 3.7
mindspore 2.0.0 tqdm
sklearn

中文数据集

THUCNews中抽取了20万条新闻标题,文本长度在20到30之间。一共10个类别,每类2万条。

类别:财经、房产、股票、教育、科技、社会、时政、体育、游戏、娱乐。

数据集划分:

数据集 数据量
训练集 18万
验证集 1万
测试集 1万

更换自己的数据集

  • 如果用字,按照数据集的格式来格式化你的数据。
  • 如果用词,提前分好词,词之间用空格隔开,python run.py --model TextCNN --word True
  • 使用预训练词向量:utils.py的main函数可以提取词表对应的预训练词向量。

使用说明

# 训练并测试:
# TextCNN
python run.py --model TextCNN

# TextRNN
python run.py --model TextRNN

# TextRNN_Att
python run.py --model TextRNN_Att

# TextRCNN
python run.py --model TextRCNN

# FastText, embedding层是随机初始化的
python run.py --model FastText --embedding random 

# DPCNN
python run.py --model DPCNN

# Transformer
python run.py --model Transformer

参数

模型都在models目录下,超参定义和模型定义在同一文件中。
