Image Steganography For Securing Intellicise Wireless Networks: "Invisible Encryption" Against Eavesdroppers

no code implementations7 May 2025 Bizhu Wang, Song Gao, Rui Meng, Haixiao Gao, Xiaodong Xu, Mengying Sun, Chen Dong, Ping Zhang, Dusit Niyato

As one of the most promising technologies for intellicise (intelligent and consice) wireless networks, Semantic Communication (SemCom) significantly improves communication efficiency by extracting, transmitting, and recovering semantic information, while reducing transmission delay.

Cross-Layer Encrypted Semantic Communication Framework for Panoramic Video Transmission

no code implementations19 Nov 2024 Haixiao Gao, Mengying Sun, Xiaodong Xu, Bingxuan Xu, Shujun Han, Bizhu Wang, Sheng Jiang, Chen Dong, Ping Zhang

In this paper, we propose a cross-layer encrypted semantic communication (CLESC) framework for panoramic video transmission, incorporating feature extraction, encoding, encryption, cyclic redundancy check (CRC), and retransmission processes to achieve compatibility between semantic communication and traditional communication systems.

Rate Splitting Multiple Access-Enabled Adaptive Panoramic Video Semantic Transmission

no code implementations26 Feb 2024 Haixiao Gao, Mengying Sun, Xiaodong Xu, Shujun Han, Bizhu Wang, JingXuan Zhang, Ping Zhang

We propose an RSMA-enabled semantic stream transmission scheme and formulate a joint problem of latency and immersive experience quality by optimizing the allocation ratios of power, common rate, and channel bandwidth, aiming to maximize the quality of service (QoS) scores for users.

Rankitect: Ranking Architecture Search Battling World-class Engineers at Meta Scale

no code implementations14 Nov 2023 Wei Wen, Kuang-Hung Liu, Igor Fedorov, Xin Zhang, Hang Yin, Weiwei Chu, Kaveh Hassani, Mengying Sun, Jiang Liu, Xu Wang, Lin Jiang, Yuxin Chen, Buyun Zhang, Xi Liu, Dehua Cheng, Zhengxing Chen, Guang Zhao, Fangqiu Han, Jiyan Yang, Yuchen Hao, Liang Xiong, Wen-Yen Chen

In industry system, such as ranking system in Meta, it is unclear whether NAS algorithms from the literature can outperform production baselines because of: (1) scale - Meta ranking systems serve billions of users, (2) strong baselines - the baselines are production models optimized by hundreds to thousands of world-class engineers for years since the rise of deep learning, (3) dynamic baselines - engineers may have established new and stronger baselines during NAS search, and (4) efficiency - the search pipeline must yield results quickly in alignment with the productionization life cycle.

Structure-Based Drug-Drug Interaction Detection via Expressive Graph Convolutional Networks and Deep Sets

1 code implementation AAAI 2022 Mengying Sun, Fei Wang, Olivier Elemento, Jiayu Zhou

In this work, we proposed a DDI detection method based on molecular structures using graph convolutional networks and deep sets.

MoCL: Data-driven Molecular Fingerprint via Knowledge-aware Contrastive Learning from Molecular Graph

1 code implementation5 Jun 2021 Mengying Sun, Jing Xing, Huijun Wang, Bin Chen, Jiayu Zhou

Second, the contrastive scheme only learns representations that are invariant to local perturbations and thus does not consider the global structure of the dataset, which may also be useful for downstream tasks.

Training deep neural models in the presence of corrupted supervisions is challenging as the corrupted data points may significantly impact the generalization performance.

Robust Collaborative Learning with Noisy Labels

no code implementations26 Dec 2020 Mengying Sun, Jing Xing, Bin Chen, Jiayu Zhou

In this paper, we study the underlying mechanism of how disagreement and agreement between networks can help reduce the noise in gradients and develop a novel framework called Robust Collaborative Learning (RCL) that leverages both disagreement and agreement among networks.
