ProxylessKD: Direct Knowledge Distillation with Inherited Classifier for Face Recognition
Weidong Shi, Guanghui Ren, Yunpeng Chen +1
Knowledge Distillation (KD) refers to transferring knowledge from a large model to a smaller one, which is widely used to enhance model performance in machine learning. It tries to…
Towards Stable Imbalanced Data Classification via Virtual Big Data Projection
Hadi Mansourifar, Weidong Shi
Virtual Big Data (VBD) proved to be effective to alleviate mode collapse and vanishing generator gradient as two major problems of Generative Adversarial Neural Networks (GANs) ver…
Vulnerability of Face Recognition Systems Against Composite Face Reconstruction Attack
Hadi Mansourifar, Weidong Shi
Rounding confidence score is considered trivial but a simple and effective countermeasure to stop gradient descent based image reconstruction attacks. However, its capability in th…
Computational Complexity Characterization of Protecting Elections from Bribery
Lin Chen, Ahmed Sunny, Lei Xu +5
The bribery problem in election has received considerable attention in the literature, upon which various algorithmic and complexity results have been obtained. It is thus natural…
One-Shot GAN Generated Fake Face Detection
Hadi Mansourifar, Weidong Shi
Fake face detection is a significant challenge for intelligent systems as generative models become more powerful every single day. As the quality of fake faces increases, the train…
Deep Synthetic Minority Over-Sampling Technique
Hadi Mansourifar, Weidong Shi
Synthetic Minority Over-sampling Technique (SMOTE) is the most popular over-sampling method. However, its random nature makes the synthesized data and even imbalanced classificatio…
Hybrid Cryptocurrency Pump and Dump Detection
Hadi Mansourifar, Lin Chen, Weidong Shi
Increasingly growing Cryptocurrency markets have become a hive for scammers to run pump and dump schemes which is considered as an anomalous activity in exchange markets. Anomaly d…
Algebraic multigrid block preconditioning for multi-group radiation diffusion equations
Xiaoqiang Yue, Shulei Zhang, Xiaowen Xu +2
The paper focuses on developing and studying efficient block preconditioners based on classical algebraic multigrid for the large-scale sparse linear systems arising from the fully…
Nonlinear Blockchain Scalability: a Game-Theoretic Perspective
Lin Chen, Lei Xu, Zhimin Gao +3
Recent advances in the blockchain research have been made in two important directions. One is refined resilience analysis utilizing game theory to study the consequences of selfish…
