What is focus numeric?

## Eric Johnson's Data Science Site!

#### Welcome!

I hope that someone out there finds this site interesting. Items posted here are not tutorials - but feel free to use them as such if you wish. I have tried to remain informal (assuming that most visitors won't be mathematicians) but have tried to keep my language precise and mathematically correct. In every case I explain what I'm doing so that any careful reader will be able to follow the logic if not the math.

Most of the items on this site are math-oriented. I want to focus on **machine learning** so please stay tuned for more content.

What is **not** on this site...

- Any of the code I have written for clients.
- Any work that I paid to do or did at my regular job. All work posted here is my own and belongs solely to me.
- Any of my ideas for websites, implementations of technologies and anything that is my valued intellectual property. You may do whatever you wish with any of the code, etc.
