Hello everyone,
My name is Chenzhe. I am a 4th year Ph.D. student in Applied Mathematics
from University of Alberta in Canada. Part of my research is about image
recovery using over-complete systems (wavelet frames), which involves some
machine learning techniques, and uses sparse optimization techniques as one
of the key steps. So I am quite interested in the project about "Low
rank/sparse optimization using Frank-Wolfe".
I checked the mailing list from last year. It seems that there was one
student from GSOC16 interested in a similar project. Is that still not done
for some special difficulties? I took a brief look of the Martin Jaggi paper,
it seems that the algorithm is not complicated by itself. So I guess most
of the time for the project would be to implement the algorithm in desired
form, and to make extensive tests? What kinds of tests are we expecting?
Also, I checked src/mlpack/core/optimizers/ and I saw the GradientDescent
class implemented. I guess I need to write a new class in similar structure?
Thanks!
Best,
Chenzhe
