1. 下载安装

安装稳定版

pip install rec4torch

安装最新版

pip install git+https://www.github.com/Tongjilibo/rec4torch.git

2. 功能

  • 核心功能:基于pytorch实现各类推荐算法(DeepFM, WideDeep, DCN, DIN, DIEN)
  • 主要区别:相对于deep-ctr, 去除对tensorflow和keras的依赖,去除重复过embedding的操作,原生支持multiclass
  • 训练过程

3. 快速上手

4. 版本说明

  • v0.0.2:20240204 更新依赖项torch4keras版本
  • v0.0.1:20221027 dcn, deepcrossing, deepfm, din, dien, wide&deep, ncf等模型,训练过程修改为传入dataloader,合并models和layers,合并简化embedding_lookup,去掉一些重复的embedding过程(提速)

5. 更新:

  • 20240204:更新依赖项torch4keras版本
  • 20221110:增加自定义的TensorDataset和collate_fn_device,支持指定device,防止显存占用多大,用out_dim和loss来替代task参数,兼容多分类
  • 20221027:增加deepcrossing, ncf, din, dien算法,使用torch4keras作为trainer
  • 20220930:初版提交, 训练过程修改为传入dataloader(参考bert4torch),合并models和layers(模型结构较简单),合并简化embedding_lookup,去掉一些重复的embedding过程(提速)
