On the Structural Generalization in Text-to-SQL
Jieyu Li, Lu Chen, Ruisheng Cao +5
Exploring the generalization of a text-to-SQL parser is essential for a system to automatically adapt the real-world databases. Previous works provided investigations focusing on l…
ISAC-Enabled Beam Alignment for Terahertz Networks: Scheme Design and Coverage Analysis
Wenrong Chen, Lingxiang Li, Zhi Chen +3
As a key pillar technology for the future 6G networks, Terahertz (THz) communications can provide high-capacity transmissions, but suffers from severe propagation loss and line-of-…
OPAL: Ontology-Aware Pretrained Language Model for End-to-End Task-Oriented Dialogue
Zhi Chen, Yuncong Liu, Lu Chen +3
This paper presents an ontology-aware pretrained language model (OPAL) for end-to-end task-oriented dialogue (TOD). Unlike chit-chat dialogue models, task-oriented dialogue models…
An Analytical Range-Angle Dependent Beam Focusing Model for Terahertz Linear Antenna Array
Lingxiang Li, Haoran Li, Zhi Chen +2
This paper considers a scenario in which the Terahertz (THz) transmitter equipped with a linear antenna array wishes to focus its beam to a desired spatial region in the array near…
DFM: Dialogue Foundation Model for Universal Large-Scale Dialogue-Oriented Task Learning
Zhi Chen, Jijia Bao, Lu Chen +10
Building a universal conversational agent has been a long-standing goal of the dialogue research community. Most previous works only focus on a small set of dialogue tasks. In this…
UniDU: Towards A Unified Generative Dialogue Understanding Framework
Zhi Chen, Lu Chen, Bei Chen +5
With the development of pre-trained language models, remarkable success has been witnessed in dialogue understanding (DU). However, current DU approaches usually employ independent…
On Multiple-Antenna Techniques for Physical-Layer Range Security in the Terahertz Band
Weijun Gao, Xuyang Lu, Chong Han +1
Terahertz (THz) communications have naturally promising physical layer security (PLS) performance in the angular domain due to the high directivity feature brought by the ultra-mas…
Delay-Phase Precoding for Wideband THz Massive MIMO
Linglong Dai, Jingbo Tan, H. Vincent Poor
Benefiting from tens of GHz bandwidth, terahertz (THz) communication is considered to be a promising technology to provide ultra-high speed data rates for future 6G wireless system…
Distributed Structured Actor-Critic Reinforcement Learning for Universal Dialogue Management
Zhi Chen, Lu Chen, Xiaoyuan Liu +1
The task-oriented spoken dialogue system (SDS) aims to assist a human user in accomplishing a specific task (e.g., hotel booking). The dialogue management is a core part of SDS. Th…
AgentGraph: Towards Universal Dialogue Management with Structured Deep Reinforcement Learning
Lu Chen, Zhi Chen, Bowen Tan +3
Dialogue policy plays an important role in task-oriented spoken dialogue systems. It determines how to respond to users. The recently proposed deep reinforcement learning (DRL) app…
Optimal Pricing for Job Offloading in the MEC System with Two Priority Classes
Lingxiang Li, Marie Siew, Tony Q. S. Quek +1
Multi-Access edge computing (MEC) is an emerging paradigm where users offload computationally intensive jobs to the Access Point (AP). Given that the AP's resources are shared by s…
Distortion Minimization for Relay Assisted Wireless Multicast
Z. Chen, P. Ho, L. Peng
The paper studies the scenario of wireless multicast with a single transmitter and a relay that deliver scalable source symbols to the receivers in a decode-and-forward (DF) fashio…
New Astrophysical Reaction Rate for the Reaction
Z. D. An, Y. G. Ma, G. T. Fan +3
A new astrophysical reaction rate for C()O has been evaluated on the basis of a global R-matrix fitting to the available experimental data. The reaction rates of…
Improved time-resolved magneto-optical Kerr effect technique and dynamic magnetization reversal mechanism of perpendicularly magnetized FePt films
X. D. Liu, Z. Xu, R. X. Gao +4
The dynamic coercivity cannot be measured rigorously by the conventional time-resolved magneto-optical Kerr effect technique because the irreversible deviation of the transient mag…
