摘要:

我们为RecSys Challenge 2016提出了工作推荐任务的解决方案。我们的工作的主要贡献是结合时序学习与序列建模,捕捉复杂的用户项活动模式,以提高工作推荐。首先,我们提出了一个基于时间的排名模型应用于历史观测和混合矩阵分解随着时间的重新加权的相互作用。其次,我们利用用户项活动中的序列属性,并开发了一个基于RNN的推荐模型。我们的解决方案在100多名参与者的挑战中获得了5个$^{th}$名次。值得注意的是,我们的RNN方法的强大性能显示了在推荐系统中采用序列建模的一个有希望的新方向。

英文摘要:

We present our solution to the job recommendation task for RecSys Challenge 2016. The main contribution of our work is to combine temporal learning with sequence modeling to capture complex user-item activity patterns to improve job recommendations. First, we propose a time-based ranking model applied to historical observations and a hybrid matrix factorization over time re-weighted interactions. Second, we exploit sequence properties in user-items activities and develop a RNN-based recommendation model. Our solution achieved 5$^{th}$ place in the challenge among more than 100 participants. Notably, the strong performance of our RNN approach shows a promising new direction in employing sequence modeling for recommendation systems.
