Teaching:
October 16, 2006: My research at IBM TJ Watson center is focused on source coding with side information. Specifically, I have worked with Dr. Luis Lastras (IBM Research) and Prof. En-hui Yang (UWaterloo) on the redundancy analysis of Slepian-Wolf coding (ISIT 2006, ITW 2006, Allerton 2006). I have also worked with Dr. Jun Chen (IBM Research) and Dr. Ashish Jagmohan (IBM Research) on the design of Slepian-Wolf codes based on factor graphs (ISIT 2006). I have also joined the efforts of Vadim Sheinin (IBM Research) and Ashish Jagmohan on the performance analysis of uniform threshold quantization in Wyner-Ziv coding (ICASSP 2006).
Notably, in the two papers presented at ISIT 2006 [Jun, He, and Jagmohan 2006], [He and Yang 2006], we have established a strong duality between Slepian-Wolf coding and channel coding. Roughly speaking, we have shown that any Slepian-Wolf coding problem is equivalent to a channel coding problem for a channel with some form of symmetry.
January 7, 2005: I have moved, after working in Prof. Yang's Multimedia Communications Lab for about 5 years and 4 months (or equivalently 16 terms). Presently I am a research staff member at IBM T. J. Watson Research Center in Yorktown Heights, NY. To reach me, you can call me at 914-945-2509(daytime) or forward your email to dakehe(at)us.ibm.com.
