AI总结:

本综述针对推荐领域多任务学习研究的空白,梳理多任务深度推荐系统的定义、分类、应用与挑战,为该领域提供系统总结。

摘要:

多任务学习(MTL)旨在将相关任务在统一模型中学习,利用任务间的共享知识实现相互提升,因推荐场景中需兼顾性能与效率的多任务预测需求,成为推荐领域的重要研究方向。尽管MTL已得到充分研究与发展,但推荐领域仍缺乏系统综述。为填补该空白,本综述对现有多任务深度推荐系统(MTDRS)进行全面梳理:首先给出MTDRS的问题定义,并将其与其他相关领域对比;接着描绘MTDRS的发展历程,从任务关系与方法学维度引入分类体系,其中任务关系分为并行、级联及辅助主任务三类,方法学分为参数共享、优化及训练机制三类;最后总结MTDRS的应用场景与公开数据集,并强调该领域的挑战与未来方向。

英文摘要:

Multi-task learning (MTL) aims at learning related tasks in a unified model to achieve mutual improvement among tasks considering their shared knowledge. It is an important topic in recommendation due to the demand for multi-task prediction considering performance and efficiency. Although MTL has been well studied and developed, there is still a lack of systematic review in the recommendation community. To fill the gap, we provide a comprehensive review of existing multi-task deep recommender systems (MTDRS) in this survey. To be specific, the problem definition of MTDRS is first given, and it is compared with other related areas. Next, the development of MTDRS is depicted and the taxonomy is introduced from the task relation and methodology aspects. Specifically, the task relation is categorized into parallel, cascaded, and auxiliary with main, while the methodology is grouped into parameter sharing, optimization, and training mechanism. The survey concludes by summarizing the application and public datasets of MTDRS and highlighting the challenges and future directions of the field.
