A Lighting Pytorch Framework for Recommendation System, Easy-to-use and Easy-to-extend.
Project description
Torch-RecHub
A Lighting Pytorch Framework for Recommendation Models, Easy-to-use and Easy-to-extend.
安装
pip install torch-rechub
主要特性
-
scikit-learn风格易用的API(fit、predict),即插即用
-
训练过程与模型定义解耦,易拓展,可针对不同类型的模型设置不同的训练机制
-
使用Pytorch原生Dataset、DataLoader,易修改,自定义数据
-
高度模块化,支持常见Layer(MLP、FM、FFM、target-attention、self-attention、transformer等),容易调用组装成新模型
-
支持常见排序模型(WideDeep、DeepFM、DIN、DCN、xDeepFM等)
-
支持常见召回模型(DSSM、YoutubeDNN、MIND、SARSRec等)
-
丰富的多任务学习支持
- SharedBottom、ESMM、MMOE、PLE、AITM等模型
- GradNorm、UWL等动态loss加权机制
-
聚焦更生态化的推荐场景
- 冷启动
- 延迟反馈
- 去偏
-
支持丰富的训练机制(对比学习、蒸馏学习等)
-
第三方高性能开源Trainer支持(Pytorch Lighting等)
-
更多模型正在开发中
快速使用
from torch_rechub.models import WideDeep, DeepFM, DIN
from torch_rechub.trainers import CTRTrainer
from torch_rechub.basic.utils import DataGenerator
dg = DataGenerator(x, y)
train_dataloader, val_dataloader, test_dataloader = dg.generate_dataloader()
model = DeepFM(deep_features=deep_features, fm_features=fm_features, mlp_params={"dims": [256, 128], "dropout": 0.2, "activation": "relu"})
ctr_trainer = CTRTrainer(model)
ctr_trainer.fit(train_dataloader, val_dataloader)
auc = ctr_trainer.evaluate(ctr_trainer.model, test_dataloader)
Note:
所有模型均在大多数论文提及的多个知名公开数据集中测试,达到或者接近论文性能。
使用案例:Examples
每个数据集将会提供
- 一个使用脚本,包含样本生成、模型训练与测试,并提供一套测评所用参数。
- 一个预处理脚本,将原始数据进行预处理,转化成csv。
- 数据格式参考文件(100条)。
- 全量数据,统一的csv文件,提供高速网盘下载链接和原始数据链接。
