The same might hold true for machines. Scientists at Purdue University and Haverford College devised an algorithm that can learn to predict new crystal recipes based on its analyses of not just chemical reactions that yielded other crystals, but also chemical reactions gone wrong. They reported their findings in a study published in the journal Nature this week. Although the study focuses on chemical applications, Alex Norquist, the study’s lead researcher, said in an interview the approach has the potential to liberate large amounts of potentially…
