Welcome (or welcome back!) to the AI for social good series! In the second part, of this two-part series of articles, we will look at how Artificial intelligence (AI) coupled with the power of open-source tools and techniques like deep learning can help us further the quest for finding extra-terrestrial intelligence! In the first part of this two-part series, we formulated our key objective and motivation behind doing this project. Briefly, we were looking at different radio-telescope signals simulated from SETI (Search for Extra-terrestrial Intelligence) Institute data. We leveraged techniques to process, analyze and visualize radio signals as spectrograms, which are basically visual representations of the raw signal.

"How could we possibly appreciate the Mona Lisa if Leonardo had written at the bottom of the canvas'The lady is smiling because she is hiding a secret from her lover'? This would shackle the viewer to reality, and I don't want this to happen to 2001." Perhaps it was the psychedelic movement of the late 1960's that saved Stanley Kubrick's tale of first contact with an extra-terrestrial intelligence from being buried in oblivion. The initial response to the film was extremely polarised if not hostile, and at the box office it wasn't a hit either. Rumour has it MGM, ready to pull the movie after a few weeks, was told by theater owners there's more people coming to the shows at last but those people were somewhat different -- a young crowd, smoking pot before the screenings.
