推荐系统预训练pre-training+跨域推荐、迁移学习场景大规模数据集（开源） A Large-scale Dataset for Transfer Learning and Pre-training in Recommendation.
数据集：包括腾讯看点和QQ浏览器的短视频视频、新闻和广告用户点击观看行为，拥有shared user数据，因此可以用于用户表征建模和迁移学习，跨域推荐，冷启动等场景，同时数据集包含了用户的画像信息，因为可以用于基于迁移学习的画像预测，详情见以下参考论文和数据集readme文件。 DataSets links for recommender systems research, in particular for transfer learning, pre-training, lifelong learning, cold start recommendation, cross-domain recommendation
