An illustration hints at how LIGO uses mirrors and laser beams to detect black hole collisions. (Google DeepMind Illustration) The Laser Interferometer Gravitational-Wave Observatory, or LIGO, has already won its researchers a Nobel Prize — and now artificial intelligence is poised to take LIGO’s search for cosmic collisions to the next level. Google DeepMind and the LIGO team say they’ve developed an AI tool called Deep Loop Shaping that has been shown to enhance the observatory’s ability to tr...
