Biography

I am a Ph.D. candidate at NLP2CT lab, University of Macau, advised by Prof. Derek F. Wong. Before that, I revieced my B.E. degree from Central China Normal University. I was a postgraduate intern at Tsinghua NLP Group and a research intern at Tencent AI Lab. My current research interests focus on deep learning for NLP, e.g., machine translation and grammar error correction.

Miscellaneous

    My first name Xuebo means studying (Xue) for a doctorate (Bo). I am nearly achieving it.
    I love swimming, every working day at UM swimming pool I swim 2,000 meters within 45 minutes.
