Updates on my research and papers, technique notes, discussion of open problems and any other topics about machine learning, compressed sensing, statistics and optimization.

We recently published a google site for Go Decomposition (GoDec), presented on ICML 2011. Now you can find all the available information and upcoming news about GoDec on

2. The MatLab code for GoDec algorithm and background modeling. Note this is a beta version, so further revision and modification for acceleration and clear readability can be expected.

3. Video for ICML 2011 presentation can be found here.

”Photon-counting compressive sensing laser radar for 3D imaging” by Gregory Howland, Paul Dixon, and John Howell@ University of Rochester. Note that, they used Figueiredo, Nowak, and Wright’s Gradient Projection algorithm and GPSR 6.0. Their idea is a hardware implementation of compressive sensing. Photon-counting laser radar is my PhD topic and i have come up with the similar idea, so I am interested in the paper. But I doubt some points about the Rochester’s idea. These days I are reading some technical content about it as well as recalling compressed sensing.

As for compressed sensing group in U Edinburgh, I just know a little about them. I am in Heriot-Watt U rather than U Edinburgh, but both have close collaboration.

well done! I knew your GoDec from Nuit Blanche’s blog!

Cheers, Ximing! Good to hear from old friend! How are you doing?

All right. Busy with my ranging and imaging experiment. Cheers. And you?

Also paper and experiments. Are u still working on compressed sensing? There is a compressed sensing group in U Edinburgh, very strong.
