A team of astronomers and computer scientists at the University of Hertfordshire have taught a machine to “see” astronomical images, using data from the Hubble Space Telescope Frontier Fields set of images of distant clusters of galaxies that contain several different types of galaxies. The technique, which uses a form of AI called unsupervised machine learning, allows galaxies to be automatically classified at high speed, something previously done by thousands of human volunteers in projects like Galaxy Zoo.


“We have not told the machine what to look for in the images, but instead taught it how to ‘see,’” said graduate student Alex Hocking. “Our aim is to deploy this tool on the next generation of giant imaging surveys where no human, or even group of humans, could closely inspect every piece of data. But this algorithm has a huge number of applications far beyond astronomy, and investigating these applications will be our next step,” said University of Hertfordshire Royal Society University Research Fellow James Geach, PhD.


The scientists are now looking for collaborators to make use of the technique in applications like medicine, where it could for example help doctors to spot tumors, and in security, to find suspicious items in airport scans.

My son, Harold, is huge into video games and video game culture. He knows more weird and deep-level memes and obscure details than you’ll ever know. Harold has convinced me to take him to the SCG Convention in Texas. To say he’s hyped and excited is to really underplay how he feels about it. As …

“I build sets and create scenes for her,” Juno explains on her website, “imaginary bedrooms in which I perform critical studies into modern rites of seduction and beauty, and the laboured construction of femininity. Objects once perceived as radical, innovative, fun and nutritious – an electronic anti-wrinkle mask, computer equipment from the 1980s, baby oil, a tin of cold meat – have become joyless and oppressive. Joyce appears alone, consumed by artifice; her glazed appearance acting as a mirror to the exhaustion felt whilst bearing the dead weight of constructed femininity.”
