HeroNet: A Hybrid Retrieval-Generation Network for Conversational Bots

1 code implementation29 Jan 2023 Bolin Zhang, Yunzhe Xu, Zhiying Tu, Dianhui Chu

Specifically, the retrieval performance is improved while the model size is reduced by training two lightweight, task-specific adapter modules that share only one underlying T5-Encoder model.

Multi-Scenario Bimetric-Balanced IoT Resource Allocation: An Evolutionary Approach

no code implementations10 Nov 2022 Jiashu Wu, Hao Dai, Yang Wang, Zhiying Tu

In this paper, we allocate IoT devices as resources for smart services with time-constrained resource requirements.

Requirements Elicitation in Cognitive Service for Recommendation

no code implementations29 Mar 2022 Bolin Zhang, Zhiying Tu, Yunzhe Xu, Dianhui Chu, Xiaofei Xu

To this end, two phases must be applied: I. Sequence planning and Real-time detection of user requirement, II. Service resource selection and Response generation.

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.
