Cool Worlds | The Weird Detector @CoolWorldsLab | Uploaded 5 years ago | Updated 20 hours ago
Arguably the greatest scientific discoveries are the unexpected ones. The discoveries that defy explanation and for which no theory or model predicted. Yet, looking for such signals is incredibly challenging. How can you look for something when you don't know what it looks like? This has been a problem we've thought about a lot here in the Cool Worlds Lab at Columbia University and this week we're thrilled to share the outcome of a new research project in this area. Graduate student Adam Wheeler presents the "Weird Detector" - an algorithm capable of finding the truly weird signals lurking in astronomical data!
