Drug-Discovery
AI Designs Chemical Weapons: Researchers retrained a system originally designed to discover new medicines to show that it could, instead, generate molecular formulas for poisons.
It’s surprisingly easy to turn a well-intended machine learning model to the dark side. In an experiment, Fabio Urbina and colleagues at Collaborations Pharmaceuticals, who had built a drug-discovery model to design useful compounds and avoid toxic ones, retrained it to generate poisons.
