Personalized Attraction Enhanced Sponsored Search with Multi-task Learning [PDF]
arXiv, 2019 We study a novel problem of sponsored search (SS) for E-Commerce platforms: how we can attract query users to click product advertisements (ads) by presenting them features of products that attract them. This not only benefits merchants and the platform, but also improves user experience.

A Brand-level Ranking System with the Customized Attention-GRU Model [PDF]
International Joint Conferences on Artificial Intelligence, 2018:
3947-3953, 2018 In e-commerce websites like Taobao, brand is playing a more important role in influencing users' decision of click/purchase, partly because users are now attaching more importance to the quality of products and brand is an indicator of quality. However, existing ranking systems are not specifically designed to satisfy this kind of demand.

Addressing the Item Cold-start Problem by Attribute-driven Active Learning [PDF]
arXiv, 2018 In recommender systems, cold-start issues are situations where no previous events, e.g. ratings, are known for certain users or items. In this paper, we focus on the item cold-start problem. Both content information (e.g. item attributes) and initial user ratings are valuable for seizing users' preferences on a new item.

Relativistic effects to the onboard BeiDou satellite clocks
Navigation, 2019 The relationship between the proper time of a satellite clock and the geocentric coordinate time (TCG) is discussed in the framework of general relativity. The influences of Earth's shape and the tidal potentials of the Sun and Moon are analyzed for onboard satellite clocks in different orbits.
