DySR: A Dynamic Representation Learning and Aligning based Model for Service Bundle Recommendation

no code implementations7 Aug 2021 Mingyi Liu, Zhiying Tu, Xiaofei Xu, Zhongjie Wang

The fundamental problem with these studies is that they ignore the evolution of services over time and the representation gap between services and requirements.

Learning Representation over Dynamic Graph using Aggregation-Diffusion Mechanism

no code implementations3 Jun 2021 Mingyi Liu, Zhiying Tu, Xiaofei Xu, Zhongjie Wang

However, relying only on aggregation to propagate information in dynamic graphs can result in delays in information propagation and thus affect the performance of the method.

LTP: A New Active Learning Strategy for CRF-Based Named Entity Recognition

1 code implementation8 Jan 2020 Mingyi Liu, Zhiying Tu, Tong Zhang, Tonghua Su, Zhongjie Wang

In this paper, we first examine traditional active learning strategies in a specific case of BiLstm-CRF that has widely used in named entity recognition on several typical datasets.
