Learning Machine Learning, Part Three: Data Wrangling

Part One and Part Two of Learning Machine Learning explored the machine learning (ML) workflow. We built and evaluated a K-nearest neighbors classification model. By far the most work for this classification project, behind the scenes, has been wrangling the input and output data. Since this sort of PHP/MySQL data wrangling is nothing like building a website, we’re using Part Three to build our wrangling skills.
