Thanks for visiting my webpage. I am a research staff member at NEC Labs America, and now I am also the head of the Media Analytics Department. My main research interests are in sparse learning, which aims to discover the optimally sparse representation of data. The concept of optimal sparseness is best described by the quote: make everything as simple as possible, but not simpler -- Albert Einstein.
