Machine learning (ML) and advanced statistics are important tools for drawing insights from large datasets. However, these techniques often require human intervention to steer computation towards meaningful results. Vizdom, a new system for interactive analytics through pen and touch, allows users to visually compose complex workflows of ML and statistics operators on an interactive whiteboard, and the backend leverages recent advances in workflow compilation techniques to run these computations at interactive speeds. Additionally, we are exploring approximation techniques for quickly visualizing partial results that incrementally refine over time.
