Artificial intelligence is getting into the odor business. Researchers at Google recently announced that they have trained an AI-powered neural network model to "map out" how a molecule's structure correlates to its scent, and it could spark a revolution in the realms of food, fragrance, and health.⁠ ⁠ Google researchers say that smell is the most difficult of the senses to quantify into machine-understandable data, and they've been working for several years to train their AI models to predict how molecules will smell by analyzing their structural makeup.
