I've started reading this book on the subject of machine learning using python. A couple years ago, I completed Andrew Ng's Coursera class on machine learning. It was great, but it went a lot into the mechanics of each algorithm. That gave me a good perspective on those algorithms. Today I want to drill into the application of those algorithms, applying them to data science and machine learning. I am only 10% through and am already excited about the capabilities of the Python libraries.
