Wait, so AI has found a 'signal of interest'? How interesting 🛸
AI is now used in virtually all areas of science to help researchers with routine classification tasks. It’s also helping our team of radio astronomers broaden the search for extraterrestrial life, and results so far have been promising.When researchers fed AI a previously studied dataset, it discovered eight signals of interest the classic algorithm missed that beats classical algorithms in signal detection tasks.
So although the idea of an AI detecting extraterrestrial intelligence sounds like the plot of an exciting science fiction novel, both terms are flawed: AI programs are not intelligent, and searches for extraterrestrial intelligence can’t find direct evidence of intelligence. Instead, radio astronomers look for radio ‘technosignatures’. These hypothesised signals would indicate the presence of technology and, by proxy, the existence of a society with the capability to harness technology for communication.
Search algorithms need to be able to sift out real technosignatures from “false positives”, and do so quickly. Our AI classifier delivers on these requirements.
