Data Science Depot is a collection of data science articles I’ve written as part of my participation in the Data Science Community on Coursera.org, interactions on Twitter @lgreski, and content I’ve posted on StackOverflow. I also post references to articles of interest, or content that I’ve used as supporting material for answers I’ve provided to students in my role as a Community Mentor in the Johns Hopkins University Data Science Specialization.
