AI could help replicate smells in danger of being lost to history

Artificial intelligence can whip up the formula to recreate a perfume based on its chemical composition.

Finally, they again used AI to minimise any mismatches between the odour values of the original mixture and the AI-generated mixture. Their ultimate recipe for one of the fragrances showed small deviations with respect to its “coumarinic” and “sharp” notes, while the other seemed to be a very precise replica., so the researchers used a limited number of molecules in their training data.

Nogueria and his colleagues have already nearly gotten there. In a few weeks, he will be off to a colleague’s lab in Ljubljana, Slovenia, to experience some of the AI-generated fragrances himself. “I am very excited to smell them,” he says.
