Simplifying and Accelerating Data Exploration

Aditya Parameswaran

Assistant Professor - UC Berkeley


Interactive data exploration tools are extremely popular; as examples, the spreadsheet tool Microsoft Excel is used by nearly 10% of the world's population, while the visual analytics tool Tableau was valued at 16B prior to its acquisition by Salesforce. Despite their popularity across a spectrum of domains, it is still challenging to use these tools to derive insights, especially on large datasets that are increasingly the norm, leading to frustration, missed opportunities and errors, and tedious manual effort. Drawing on examples from spreadsheets and visual analytics, we will describe our work on simplifying and accelerating data exploration, as well as some takeaways from our experience.
