I am Xiaoyong (Brian) Yuan,

Second-year Ph.D student of Computer & Information Science & Engineering Department, University of Florida.

My advisor is Dr. Xiaolin (Andy) Li. I joined Andy's Scalable Software Systems Laboratory (S3Lab) in Fall, 2015. Before joining the Gator Nation, I received my M.E. in Computer Engineering from Peking University (2015), advised by Dr. Ying Li, and B.S. in Mathematics from Fudan University (2012).

My research interests are Deep Learning, Security and Distributed Systems. I'm willing to build large systems for deep learning. My CV is available here.

I come from Shanghai, a modern and beautiful city in China. When I'm not working, I like a lot of sports (e.g. Soccer, Swimming, Badminton, Basketball, Sanshou, Shengji, and Skiing). I'm a big fan of Shanghai Shenhua and A.C. Milan.

  • DeepFaceAttack

    Face recognition is one of the essential characteristics of the biometric system. The performance of face recognition has been dramatically improved by deep learning algorithms and is very close to the human benchmark. However, the deep learning models are vulnerable to specially crafted adversarial samples. We propose a key point enhanced attacking approach to generate adversarial samples and disturb the face recognition model. We conduct our experiments on LFW dataset. Our results show that this approach can craft famous face which can still be recognized by a human but misclassified by the deep learning model. We reduce the accuracy of face recognition system from 98% to 69.5% within acceptable changes of images. [Poster]

  • DeepDetection: Identifying DDoS Attack via Deep Learning

    Distributed Denial of Service (DDoS) attacks grow rapidly and become one of the major threats to the Internet. Automatically detecting DDoS attack packets is one of the main defense mechanisms. Conventional solution monitors network traffic and identifies attack activities from legitimate network traffic based on statistical divergence. Machine learning is another method to improve identifying performance based on statistical features. However, conventional machine learning techniques are limited by the shallow representation models. We propose a deep learning based DDoS attack detection approach (called DeepDetection). Deep learning approach can automatically extract high level features from low level ones and gain powerful representation and inference. We build a recurrent deep neural network to learn patterns from sequences of network traffic and trace network attack activities in both long and short terms.
