Argues that 80% of analytic effort is data cleaning and that automation alone fails, offering a human-in-the-loop system called predictive interaction that watches live visuals of raw rows, predicts transformations, shows previews, and appends chosen steps into a reusable script. Demonstrates anomaly detection, example-based pattern learning that converges with few examples, interactive joins, and the ability to export to Hadoop so the recorded pipeline runs at scale. The demo shows practical reduction in manual cleanup time.
