We've covered a lot of material here and I hope that you at least understand the concepts and have a little bit of hands-on experience with most of the techniques that are used in data science today. It's a very broad field, so we've touched on a little bit of everything there. So, you know, congratulations again.
If you want to further your career in this field, what I'd really encourage you to do is talk to your boss. If you work at...
