I presented at Utah Code Camp 2015 on machine learning with the Google Prediction API. IPython notebooks are available on GitHub, or they can be viewed directly with the IPython Notebook Viewer here:

• Converting Raw Input Files
• Machine Learning with Google Prediction API
• Taylor Swift Prediction with scikit-learn
• Taylor Swift …

I presented on machine learning and prediction to the Big Data Utah meetings as part of StartSLC 2015. Check out the the slides!

I competed in this year's edition of the Utah Data Competition, a local data science competition. The semiconductor yield prediction problem seemed simple enough on the surface, but it ultimately proved to be quite challenging. I attempted several modeling approaches but eventually converged on two that received most of my …

After updating to IPython 2.0, I decided to get rmagic working on a Windows 8.1 install. These instructions should probably work with IPyhon 1.X, too, although I have not tried.

R on Windows

Behind the scenes, rmagic assumes that a working version of R is available on …

Here's a quick IPython notebook gist about FFTs in Python. Ironically, most tutorials don't describe how to scale and format the FFT output so that sinusoidal amplitudes are correctly displayed. Sometimes that's important. If you don't have IPython installed, the notebook can be viewed using the awesome IPython Notebook Viewer …
