DeRoo Group Using AI to Identify Astronomical Outliers

In an article published in the March 2021 Iowa Magazine, the DeRoo Group was noted as one of several researchers using artificial intelligence to drive discovery. The University of Iowa team is teaching computers to categorize celestial objects on their own, then flag for further examination the phenomena that don't fit into neat categories.
