Process-and-Forward: Deep Joint Source-Channel Coding Over Cooperative Relay Networks

no code implementations15 Mar 2024 Chenghong Bian, Yulin Shao, Haotian Wu, Emre Ozfatura, Deniz Gunduz

In the proposed scheme, the source transmits information in blocks, and the relay updates its knowledge about the input signal after each block and generates its own signal to be conveyed to the destination.

TDCGL: Two-Level Debiased Contrastive Graph Learning for Recommendation

no code implementations1 Oct 2023 Yubo Gao, Haotian Wu

Specifically, we design the Two-Level Debiased Contrastive Learning (TDCL) and deploy it in the KG, which is conducted not only on User-Item pairs but also on User-User pairs for modeling higher-order relations.

A Graph Reconstruction by Dynamic Signal Coefficient for Fault Classification

no code implementations30 May 2023 Wenbin He, Jianxu Mao, Yaonan Wang, Zhe Li, Qiu Fang, Haotian Wu

To improve the performance in identifying the faults under strong noise for rotating machinery, this paper presents a dynamic feature reconstruction signal graph method, which plays the key role of the proposed end-to-end fault diagnosis model.

Features-over-the-Air: Contrastive Learning Enabled Cooperative Edge Inference

no code implementations17 Apr 2023 Haotian Wu, Nitish Mital, Krystian Mikolajczyk, Deniz Gündüz

We study the collaborative image retrieval problem at the wireless edge, where multiple edge devices capture images of the same object, which are then used jointly to retrieve similar images at the edge server over a shared multiple access channel.

Collaborative Semantic Communication for Edge Inference

no code implementations10 Jan 2023 Wing Fei Lo, Nitish Mital, Haotian Wu, Deniz Gündüz

We study the collaborative image retrieval problem at the wireless edge, where multiple edge devices capture images of the same object from different angles and locations, which are then used jointly to retrieve similar images at the edge server over a shared multiple access channel (MAC).

Space-time design for deep joint source channel coding of images Over MIMO channels

1 code implementation30 Oct 2022 Chenghong Bian, Yulin Shao, Haotian Wu, Deniz Gunduz

We propose novel deep joint source-channel coding (DeepJSCC) algorithms for wireless image transmission over multi-input multi-output (MIMO) Rayleigh fading channels, when channel state information (CSI) is available only at the receiver.

GGViT:Multistream Vision Transformer Network in Face2Face Facial Reenactment Detection

no code implementations12 Oct 2022 Haotian Wu, Peipei Wang, Xin Wang, Ji Xiang, Rui Gong

The compression of videos on social media has destroyed some pixel details that could be used to detect forgeries.

A High-Performance Customer Churn Prediction System based on Self-Attention

no code implementations3 Jun 2022 Haotian Wu

Therefore, a novel algorithm, a hybrid neural network with self-attention enhancement (HNNSAE), is proposed in this paper to improve the efficiency of feature screening and feature extraction, consequently improving the model's predictive performance.

Cyclic Arbitrage in Decentralized Exchanges

no code implementations21 Apr 2021 Ye Wang, Yan Chen, Haotian Wu, Liyi Zhou, Shuiguang Deng, Roger Wattenhofer

We find that traders have executed 292, 606 cyclic arbitrages over eleven months and exploited more than 138 million USD in revenue.

Minimum Potential Energy of Point Cloud for Robust Global Registration

no code implementations11 Jun 2020 Zijie Wu, Yaonan Wang, Qing Zhu, Jianxu Mao, Haotian Wu, Mingtao Feng, Ajmal Mian

Different from the most existing point set registration methods which usually extract the descriptors to find correspondences between point sets, our proposed MPE alignment method is able to handle large scale raw data offset without depending on traditional descriptors extraction, whether for the local or global registration methods.
