Mixture of Virtual-Kernel Experts for Multi-Objective User Profile Modeling
Zhenhui Xu, Meng Zhao, Liqun Liu +3
In industrial applications like online advertising and recommendation systems, diverse and accurate user profiles can greatly help improve personalization. Deep learning is widely…
MC-BERT: Efficient Language Pre-Training via a Meta Controller
Zhenhui Xu, Linyuan Gong, Guolin Ke +5
Pre-trained contextual representations (e.g., BERT) have become the foundation to achieve state-of-the-art results on many NLP tasks. However, large-scale pre-training is computati…
Equivalence-Based Model of Dimension-Varying Linear Systems
Daizhan Cheng, Zhenhui Xu, Tielong Shen
Dimension-varying linear systems are investigated. First, a dimension-free state space is proposed. A cross dimensional distance is constructed to glue vectors of different dimensi…
