Data analysts routinely report spending more time “wrangling” their data than performing analysis per se. In this tutorial we focus on the ever-present yet oft-overlooked challenges of Data Transformation, including discovery, structure, content and curation. We emphasize recent approaches that jointly emphasize interaction and inference, leveraging both human acuity and computational power.
