QIENet: Quantitative irradiance estimation network using recurrent neural network based on satellite remote sensing data

no code implementations1 Dec 2023 Longfeng Nie, Yuntian Chen, Dongxiao Zhang, Xinyue Liu, Wentian Yuan

Specifically, the temporal and spatial characteristics of remote sensing data of the satellite Himawari-8 are extracted and fused by recurrent neural network (RNN) and convolution operation, respectively.

Multi-State Brain Network Discovery

no code implementations4 Nov 2023 Hang Yin, Yao Su, Xinyue Liu, Thomas Hartvigsen, Yanhua Li, Xiangnan Kong

We refer to such brain networks as multi-state, and this mixture can help us understand human behavior.

Gaussian Mixture Graphical Lasso with Application to Edge Detection in Brain Networks

no code implementations13 Jan 2021 Hang Yin, Xinyue Liu, Xiangnan Kong

Existing works mainly focus on unimodal distributions, where it is usually assumed that the observed activities aregenerated from asingleGaussian distribution (i. e., one graph). However, this assumption is too strong for many real-worldapplications.

Multi-task Learning of Spoken Language Understanding by Integrating N-Best Hypotheses with Hierarchical Attention

no code implementations COLING 2020 Mingda Li, Xinyue Liu, Weitong Ruan, Luca Soldaini, Wael Hamza, Chengwei Su

The comparison shows that our model could recover the transcription by integrating the fragmented information among hypotheses and identifying the frequent error patterns of the ASR module, and even rewrite the query for a better understanding, which reveals the characteristic of multi-task learning of broadcasting knowledge.

Enhance Robustness of Sequence Labelling with Masked Adversarial Training

no code implementations Findings of the Association for Computational Linguistics 2020 Luoxin Chen, Xinyue Liu, Weitong Ruan, Jianhua Lu

Adversarial training (AT) has shown strong regularization effects on deep learning algorithms by introducing small input perturbations to improve model robustness.

Improving Spoken Language Understanding By Exploiting ASR N-best Hypotheses

no code implementations11 Jan 2020 Mingda Li, Weitong Ruan, Xinyue Liu, Luca Soldaini, Wael Hamza, Chengwei Su

The NLU module usually uses the first best interpretation of a given speech in downstream tasks such as domain and intent classification.

Signed Distance-based Deep Memory Recommender

1 code implementation1 May 2019 Thanh Tran, Xinyue Liu, Kyumin Lee, Xiangnan Kong

Personalized recommendation algorithms learn a user's preference for an item by measuring a distance/similarity between them.

TreeGAN: Syntax-Aware Sequence Generation with Generative Adversarial Networks

no code implementations22 Aug 2018 Xinyue Liu, Xiangnan Kong, Lei Liu, Kuorong Chiang

To address these issues, we study the problem of syntax-aware sequence generation with GANs, in which a collection of real sequences and a set of pre-defined grammatical rules are given to both discriminator and generator.
