100DaysOfMLCode

The creation of this repository was inspired by Siraj Raval's challenge to code machine learning for at least an hour everyday for 100 days.

I nervously accepted this challenge in addition to working full time and taking 6 hours of graduate courseowrk in the 2018 summer semester. I will use this repository to store code, jupyter notebook examples, and thought processes.
