Grounding Description-Driven Dialogue State Trackers with Knowledge-Seeking Turns

Alexandru Coca, Bo-Hsiang Tseng, Jinghong Chen +4

Schema-guided dialogue state trackers can generalise to new domains without further training, yet they are sensitive to the writing style of the schemata. Augmenting the training s…

Semantic reconstruction of continuous language from MEG signals

Bo Wang, Xiran Xu, Longxiang Zhang +3

Decoding language from neural signals holds considerable theoretical and practical importance. Previous research has indicated the feasibility of decoding text or speech from invas…

A DenseNet-based method for decoding auditory spatial attention with EEG

Xiran Xu, Bo Wang, Yujie Yan +2

Auditory spatial attention detection (ASAD) aims to decode the attended spatial location with EEG in a multiple-speaker setting. ASAD methods are inspired by the brain lateralizati…

First Principles and Machine Learning Identify Key Pairing Strength Factors of Cuprate Superconductors

Xinyu He, Ning Chen, Jingpei Chen +2

By using band structure calculations of quantum mechanical theory, some important peaks of DoS (Density of States) were obtained and classified based on crystal structure laws of c…

Higher-order exceptional points in loss-free waveguide arrays with negative-index materials

Xin-Zhe Zhang, Li-Ting Wu, Ru-Zhi Luo +1

Negative-index materials (NIMs) are shown to support optical anti-parity-time (anti-PT) symmetry even when they are lossless. Here we prove the feasibility in achieving higher-orde…

Non-Hermitian guided modes and exceptional points using loss-free negative-index materials

Li-Ting Wu, Xin-Zhe Zhang, Ru-Zhi Luo +1

We analyze the guided modes in coupled waveguides made of negative-index materials without gain or loss. We show that it supports non-Hermitian phenomenon on the existence of guide…

Revisit the Poynting vector in PT-symmetric coupled waveguides

Xin-Zhe Zhang, Ru-Zhi Luo, Jing Chen

We show that the time-averaged Poynting vector in parity-time (PT ) symmetric coupled waveguides is always positive and cannot explain the stopped light at exceptional points (EPs)…
