In this episode, we have Michael Correll and Jeff Heer from the University of Washington to talk about a novel visualization technique they developed called “Surprise Maps”: a new kind of map which visualizes what is most surprising in a dataset.

Using their own words: “The idea behind Surprise Maps is that when we look at data, we often have various models of expectation: things we expect to see, or not see, in our data. If we have these models, we can also measure deviation or difference from these models. This deviation is the unexpected, the data that surprise us.

On the show we talk about how they came up with the idea for Surprise Maps, how they work, and potential applications and extensions for the technique.

Enjoy the show!
