Semantic Communication-Enabled Wireless Adaptive Panoramic Video Transmission

no code implementations26 Feb 2024 Haixiao Gao, Mengying Sun, Xiaodong Xu, Shujun Han

In this paper, we propose an adaptive panoramic video semantic transmission (APVST) network built on the deep joint source-channel coding (Deep JSCC) structure for the efficient end-to-end transmission of panoramic videos.

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.

Learning Deep Neural Networks under Agnostic Corrupted Supervision

no code implementations12 Feb 2021 Boyang Liu, Mengying Sun, Ding Wang, Pang-Ning Tan, Jiayu Zhou

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

Provable Robust Learning under Agnostic Corrupted Supervision

no code implementations1 Jan 2021 Boyang Liu, Mengying Sun, Ding Wang, Pang-Ning Tan, Jiayu Zhou

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.

Subspace Network: Deep Multi-Task Censored Regression for Modeling Neurodegenerative Diseases

1 code implementation ICLR 2018 Mengying Sun, Inci M. Baytas, Liang Zhan, Zhangyang Wang, Jiayu Zhou

Over the past decade a wide spectrum of machine learning models have been developed to model the neurodegenerative diseases, associating biomarkers, especially non-intrusive neuroimaging markers, with key clinical scores measuring the cognitive status of patients.
