Self-Supervised Facial Representation Learning with Facial Region Awareness

no code implementations4 Mar 2024 Zheng Gao, Ioannis Patras

Recent efforts toward this goal are limited to treating each face image as a whole, i. e., learning consistent facial representations at the image-level, which overlooks the consistency of local facial representations (i. e., facial regions like eyes, nose, etc).

Self-Supervised Representation Learning with Cross-Context Learning between Global and Hypercolumn Features

no code implementations25 Aug 2023 Zheng Gao, Chen Feng, Ioannis Patras

Inspired by cross-modality learning, we extend this existing framework that only learns from global features by encouraging the global features and intermediate layer features to learn from each other.

FrFT based estimation of linear and nonlinear impairments using Vision Transformer

no code implementations25 Aug 2023 Ting Jiang, Zheng Gao, Yizhao Chen, Zihe Hu, Ming Tang

To comprehensively assess optical fiber communication system conditions, it is essential to implement joint estimation of the following four critical impairments: nonlinear signal-to-noise ratio (SNRNL), optical signal-to-noise ratio (OSNR), chromatic dispersion (CD) and differential group delay (DGD).

Detecting User Community in Sparse Domain via Cross-Graph Pairwise Learning

no code implementations6 Sep 2020 Zheng Gao, Hongsong Li, Zhuoren Jiang, Xiaozhong Liu

In this paper, our model, Pairwise Cross-graph Community Detection (PCCD), is proposed to cope with the sparse graph problem by involving external graph knowledge to learn user pairwise community closeness instead of detecting direct communities.

Community Detection

Efficient Personalized Community Detection via Genetic Evolution

no code implementations6 Sep 2020 Zheng Gao, Chun Guo, Xiaozhong Liu

Personalized community detection aims to generate communities associated with user need on graphs, which benefits many downstream tasks such as node recommendation and link prediction for users, etc.

Typilus: Neural Type Hints

3 code implementations6 Apr 2020 Miltiadis Allamanis, Earl T. Barr, Soline Ducousso, Zheng Gao

The network uses deep similarity learning to learn a TypeSpace -- a continuous relaxation of the discrete space of types -- and how to embed the type properties of a symbol (i. e. identifier) into it.

AMAD: Adversarial Multiscale Anomaly Detection on High-Dimensional and Time-Evolving Categorical Data

no code implementations12 Jul 2019 Zheng Gao, Lin Guo, Chi Ma, Xiao Ma, Kai Sun, Hang Xiang, Xiaoqiang Zhu, Hongsong Li, Xiaozhong Liu

Anomaly detection is facing with emerging challenges in many important industry domains, such as cyber security and online recommendation and advertising.

Neural Related Work Summarization with a Joint Context-driven Attention Mechanism

1 code implementation EMNLP 2018 Yongzhen Wang, Xiaozhong Liu, Zheng Gao

Conventional solutions to automatic related work summarization rely heavily on human-engineered features.

edge2vec: Representation learning using edge semantics for biomedical knowledge discovery

1 code implementation7 Sep 2018 Zheng Gao, Gang Fu, Chunping Ouyang, Satoshi Tsutsui, Xiaozhong Liu, Jeremy Yang, Christopher Gessner, Brian Foote, David Wild, Qi Yu, Ying Ding

We propose this method for its added value relative to existing graph analytical methodology, and in the real world context of biomedical knowledge discovery applicability.
