Derek Hao Hu

I am a PhD Candidate at the Department of Computer Science and Engineering, HKUST. My supervisor is Prof. Qiang Yang. I'm mainly doing research on sensor-based activity recognition using machine learning and data mining techniques. Besides, I am also fond of programming contests. You can know more about me from my CV [pdf].

I also maintain a selected list of upcoming CS conference deadlines.
