Software and Models

We provide various models and software packages (including source codes) for downloads. A few stats. on our work as of 2018:

  • Refereed, international papers: About 80.
  • Total citations: About 2700 (Google scholar).
  • SW downloads: About 1k to 2k per year

We also give tutorials or talks on our SWs. Talk slides and other materials of those talks are too.


Open source projects

We try to release source codes of all of our research activities. As a result, there are too many of them. We list codes released before 2016.
Some of recent ones are at github yoonlab, github sglab or individual paper webpage.
