Artificial Intelligence bot recognise galaxies in deep space: A group of scientists has shown an Artificial Intelligence (AI) program – that used to recognize faces on Facebook – to recognize galaxies in deep space. The AI bot named “ClaRAN” scan pictures taken by radio telescopes. Its activity is to spot radio galaxies – galaxies that radiate ground-breaking radio planes from supermassive black holes at their focuses.
ClaRAN is the brainchild of big data master Dr. Chen Wu and astronomer Dr. Ivy Wong from The University of Western Australia node of the International Center for Radio Astronomy Research (ICRAR). Black holes are found at the focal point of most, if not all, galaxies.
Dr. Wong said” “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 programmes to figure out where the galaxy is. That’s what we’re trying to teach ClaRAN to do,” she added.
“ClaRAN” grew out of an open source version of Microsoft and Facebook’s object detection software, said Dr. Wu, adding that the programme was overhauled and trained to recognize galaxies instead of people.
ClaRAN itself is an open source and publicly available on Microsoft-owned GitHub. Traditional computer algorithms are able to correctly identify 90 percent of the sources.
“That still leaves 10 percent or seven million ‘difficult’ galaxies that have to be eyeballed by a human due to the complexity of their extended structures,” Dr. Wong said.
“If ClaRAN reduces the number of sources that require visual classification down to one percent, this means more time for our citizen scientists to spend looking at new types of galaxies,” she added in a paper published in the journal Monthly Notices of the Royal Astronomical Society.
“ClaRAN” has huge implications for how telescope observations are processed.
