Hi. Nice to meet you. I am interested in your projects. Hope more connections.
Welcome being here and welcome any discussions!
Hello! I just wanted to ask if you ever have any problems with hackers?
My last blog (wordpress) was hacked and I ended up losing several weeks of hard work
due to no back up. Do you have any methods to stop hackers?
maybe you have interest on this one “Constructing L2-Graph For Subspace Learning and Segmentation ” from “http://arxiv.org/abs/1209.0841” arvix 2012
