New detections mark the first time that machine learning techniques have been used to directly detect a fast radio transient. Successful application of machine learning for signal detection promises to open up new avenues for identifying signals from extraterrestrial intelligence.
September 10, 2018 – Mountain View, CA – Researchers at Breakthrough Listen – the initiative to find signs of intelligent life in the universe – have applied machine learning techniques to detect 72 new fast radio bursts emanating from the "repeater" FRB 121102. Fast radio bursts, or FRBs, are bright pulses of radio emission, just milliseconds in duration, thought to originate from distant galaxies. Most FRBs have been witnessed during just a single outburst. In contrast, FRB 121102 is the only one to date known to emit repeated bursts, including 21 seen during Breakthrough Listen observations made in 2017 with the Green Bank Telescope (GBT) in West Virginia.
The source and mechanism of FRBs are still mysterious. Previous studies have shown that the bursts from 121102 are emanating from a galaxy 3 billion light years from Earth, but the nature of the object emitting them is still unknown. Theories range from highly magnetized neutron stars, blasted by gas streams near to a supermassive black hole, to suggestions that the burst properties are consistent with signatures of technology developed by an advanced civilization.
“Not all discoveries come from new observations,” remarked Pete Worden, Executive director of the Breakthrough Initiatives which include Listen, “In this case, it was smart, original thinking applied to an existing dataset. It has advanced our knowledge of one of the most tantalizing mysteries in astronomy.”

1) - There is no AI . "Lipstick on a pig" marketing ploy (algorithms are not AI and have been around since calculus was introduced.)
2) - I am betting neutron star due to the radio waves detected.
But , I like the idea in general .

OP, this is inetresting... I understand the signal is 3 billion years old. I suspect not intelligent life.
