Since the previous post was fairly popular, I went ahead and built a small shell script (also below) to ease the process of building the OS X Shiny-gist application.

After copying the script to a place you can run it from in your PATH and executing a “chmod a+x ...

This is part two of a three-part blog series on building a DGA classifier and it is split into the three phases of building a classifier: 1) Data preparation 2) Feature engineering and 3) Model selection (this post)

Back in part 1, we prepared the data and we are starting ...

This will be a three-part blog series on building a DGA classifier and will be split into three logical phases of building a classifier: 1) Data preparation (this) 2) Feature engineering and 3) Model selection. And before I get too far into this, I want to give a huge thank ...
