Replicating Rare Fragrances with AI: Norwegian Researchers Use Machine Learning to Preserve Scents

TL;DR

• Norwegian researchers use machine learning to replicate rare and obscure fragrances
• AI-generated molecules closely mimic target scents, potentially rescuing rare fragrances from extinction
• This method could enable an efficient, replicable process for creating perfumes and offer a cheaper, more sustainable solution for the perfume industry

Preserving Rare Fragrances with AI

Researchers from the Norwegian University of Science and Technology have used machine learning to replicate rare and obscure fragrances, potentially revolutionising the perfume industry. By mapping molecules to different scents with a neural network, the team can generate new molecules that closely mimic target scents, potentially rescuing rare fragrances from extinction.

Methodology Breakdown To Replicate Fragrances With AI

The team’s methodology involves analyzing target fragrances to understand their scent profiles, including their scent families and intensity. They then use a Gated Graph Neural Network (GGNN) trained on a vast database of molecules to generate new molecules that could potentially replicate the target fragrance. The final stage involves optimizing the perfume formulation to match the original scent.

Benefits for the Perfume Industry

This AI-based method could enable an efficient, replicable process for creating perfumes, a task that typically requires considerable trial and error. It could also offer a cheaper and more sustainable solution for the perfume industry, which currently faces high costs and long development times. Expanding the database to include more complex molecules could enhance the accuracy of AI-generated fragrances.
