Large Scale Product Graph Construction for Recommendation in E-commerce

no code implementations12 Oct 2020 Xiaoyong Yang, Yadong Zhu, Yi Zhang, Xiaobo Wang, Quan Yuan

Building a recommendation system that serves billions of users on daily basis is a challenging problem, as the system needs to make astronomical number of predictions per second based on real-time user behaviors with O(1) time complexity.

User Validation of Recommendation Serendipity Metrics

no code implementations27 Jun 2019 Li Chen, Ningxia Wang, Yonghua Yang, Keping Yang, Quan Yuan

Though it has been recognized that recommending serendipitous (i. e., surprising and relevant) items can be helpful for increasing users' satisfaction and behavioral intention, how to measure serendipity in the offline environment is still an open issue.

Blind Motion Deblurring with Cycle Generative Adversarial Networks

no code implementations7 Jan 2019 Quan Yuan, Junxia Li, Lingwei Zhang, Zhefu Wu, Guangyu Liu

Blind motion deblurring is one of the most basic and challenging problems in image processing and computer vision.


Bridging Collaborative Filtering and Semi-Supervised Learning: A Neural Approach for POI Recommendation

no code implementations1 Aug 2017 Carl Yang, Lanxiao Bai, Chao Zhang, Quan Yuan, J. Han profile

In this work, we propose to devise a general and principled SSL (semi-supervised learning) framework, to alleviate data scarcity via smoothing among neighboring users and POIs, and treat various context by regularizing user preference based on context graphs.
