Title: Advanced Data Preparation for Supervised Machine Learning

Brief abstract: Dr. Nina Zumel and Dr. John Mount will present methods for advanced data preparation for supervised machine learning. In particular we will show how to safely pre-process high cardinality categorical variables for later use. We will spend time on the important points of cross or out of sample methods to reduce over-fit. We will work theory and examples, and show how the vtreat package can be used in projects. We wil also preview chapter 8 of Practical Data Science with R, 2nd Edition: Advanced Data Preparation.
