I am Xiaoyong (Brian) Yuan,

Fourth-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. I also closely work with Dr. Daniela Seabra Oliveira. 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 include Deep Learning, Security, and Distributed Systems. CV

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.

  • Generalized Batch Normalization

    Utilizing recently introduced concepts from statistics and quantitative risk management, we present a general variant of Batch Normalization (BN) that offers accelerated convergence of Neural Network training compared to conventional BN. In general, we show that mean and standard deviation are not always the most appropriate choice for the centering and scaling procedure within the BN transformation, particularly if ReLU follows the normalization step. We present a Generalized Batch Normalization (GBN) transformation, which can utilize a variety of alternative deviation measures for scaling and statistics for centering, choices which naturally arise from the theory of generalized deviation measures and risk theory in general. When used in conjunction with the ReLU non-linearity, the underlying risk theory suggests natural, arguably optimal choices for the deviation measure and statistic. Utilizing the suggested deviation measure and statistic, we show experimentally that training is accelerated more so than with conventional BN, often with improved error rate as well. Overall, we propose a more flexible BN transformation supported by a complimentary theoretical framework that can potentially guide design choices.

  • 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.
