基于注意力的混合密度递归网络在历史推荐中的应用

Attention-based Mixture Density Recurrent Networks for History-based Recommendation

eBay;New York University(纽约大学)

Tian Wang, Kyunghyun Cho

摘要:

个性化的基于历史的推荐的目标是自动输出一个分布在所有的项目给定的一系列以前购买的用户。在这项工作中,我们提出了一种新的方法,使用一个经常性的网络来总结购买的历史,连续的向量表示项目的可扩展性,和一个新的基于注意力的经常性混合密度网络,它输出每个组件的混合物顺序,建模多模态条件分布。我们在两个公开的数据集MovieLens-20 M和RecSys 15上评估了所提出的方法。实验表明,所提出的方法,明确建模的多模态性质的预测分布,是能够提高性能在各种基线的精度,召回率和nDCG。

英文摘要:

The goal of personalized history-based recommendation is to automatically output a distribution over all the items given a sequence of previous purchases of a user. In this work, we present a novel approach that uses a recurrent network for summarizing the history of purchases, continuous vectors representing items for scalability, and a novel attention-based recurrent mixture density network, which outputs each component in a mixture sequentially, for modelling a multi-modal conditional distribution. We evaluate the proposed approach on two publicly available datasets, MovieLens-20M and RecSys15. The experiments show that the proposed approach, which explicitly models the multi-modal nature of the predictive distribution, is able to improve the performance over various baselines in terms of precision, recall and nDCG.
