“Interacting with the Shadow of Data” at noon on Thursday 9/5 in Olin 268

Student Colloquium talk by Professor J.T. Fry, Bucknell University

Title: Interacting with the Shadow of Data

Abstract:  In our first statistics class, we learn how to build a scatterplot to visualize two variables at once. But what happens when we have many variables? Projection methods such as Principal Component Analysis (PCA) can create 2D pictures of higher-dimensional data, much like how the sun projects our 3D body into a 2D shadow. However, exploring these high-dimensional datasets can be complicated. In this talk, we present a visual analytics model that allows the user to combine their personal knowledge with a projection method to find novel ways of exploring the data.
