摘要:

近来涌现一批研究工作探讨如何将预训练技术应用在推荐场景下并构造预训练任务,以此提升最终的推荐性能。对现有的基于预训练的推荐模型研究进展进行重点综述;并对不同的预训练方法进行分类和比较,在3个推荐系统基准数据集上对一些代表性模型进行实验和分析,相关的数据集和代码已开源;最后对预训练的推荐模型的未来发展趋势进行总结和展望。

关键词: 推荐系统, 综述, 预训练模型, 自监督学习

Abstract:

Plenty of recent studies explores the application of pre-training techniques within the context of recommendation scenarios and the design of pre-training tasks in order to enhance the overall performance of recommendation. This paper extensively reviews the progress in research of recommendation models based on pre-training, classifies and compares different pre-training methods, and conducts extensive experiments and analyses on some representative models using three benchmark datasets for recommendation systems. The datasets and codes have been made open source. Finally, we summarize and prospect the future development trend of recommendation models based on pre-training.

Key words: recommendation system, survey, pre-training model, self-supervised learning
