Artificial Intelligence breakthrough: Google has taught an AI to discern different smells

What may register as woody to one person appear earthy to someone else. Some molecules may seem similar on a molecular level but they have differing scents when arranged in mirror images, causing problems for AI. However, the Google researchers believe the cutting-edge system may help advance artificial olfaction and help it keep pace with other senses bolstered or mimicked by AI. The Google team wrote: "Based on these early results with graph neural networks for molecular properties, we hope machine learning can eventually do for olfaction what it has already done for vision and hearing."
