Researchers have taught an artificial intelligence program used to recognize faces on Facebook to identify galaxies in deep space. The result is an AI bot named ClaRAN that scans images taken by radio telescopes.
Its job is to spot radio galaxies–galaxies that emit powerful radio jets from supermassive black holes at their centers. Black holes are found at the center of most, if not all, galaxies. These supermassive black holes occasionally burp out jets that can be seen with a radio telescope.
Over time, the Jets can stretch a long way from their host galaxies, making it difficult for traditional computer programs to figure out where the galaxy is. ClaRAN grew out of an open source version of Microsoft and Facebook’s object detection software. The program was completely overhauled and trained to recognize galaxies instead of people.
ClaRAN itself is also open source and publicly available on GitHub. The traditional computer algorithms are able to correctly identify 90 percent of the sources.
The new generation of programmers spend 99 percent of their time crafting the best quality data sets and then train the AI algorithms to optimize the rest.
