Search for Extraterrestrial Intelligence (SETI) Using Artificial Intelligence (AI)

The search for extraterrestrial intelligence (SETI) has been an ongoing endeavour for decades, and now, artificial intelligence (AI) is being used to find evidence of alien life. Telescopes have been set up from hills of West Virginia to the flats of rural Australia in a bid to listen to signals from technologically advanced civilizations. The biggest challenge for scientists is to differentiate signals from human or Earth technology from the kind of signals they would be looking for from technology elsewhere in the galaxy. Machine-learning algorithms are being used as they are trained on large amounts of data and can learn to recognize features of Earthly interference, making them very good at filtering out the noise. Alternative methods such as algorithms that look for signals matching what astronomers think alien beacons could look like are being used as well.
