Machine Learning for Scent: Learning Generalizable Perceptual Representations of Small Molecules


Oct 24 2019 Google AI

Our research team is using graph neural networks to predict the olfactory properties of molecules, expanding our understanding of smell & odor, with potential applications ranging from odorant synthesis to scent digitization. Learn more at

What is SMELLING @GoogleAI? Artificial Intelligence can use graph neural networks to identify molecules & predict smells by understanding the relationship between a molecule’s structure & its odour using structure-odor relationship (QSOR) modeling. Read

The science of smell lags behind many other fields. But researchers at Google Brain have a new breakthrough: they trained machine-learning algorithms to predict molecules’ smell based on their structures. This could help answer long-standing questions.

From facial to olfactory identity! Aligned with the sensory perception by IBM & Symrise fragrance. Awesome to see “smell” treated like a multi-label classification & novel concept of “odor embedding,” similar to RGB’s treatment as an embedding for vision. I can SMELL the future!

2/3 A new preprint uses graph neural networks to turn molecular structure into vectors. The representation they learned from GoodScents and Leffingwell databases performed well on a very different task--the DREAM Olfaction Challenge.

Graph NN can predict odor from a molecule's structure better than existing methods, and provide a meaningful odor space where similar scents are clustered. Similar to visual and auditory senses, NN can (at least) simulate smell sense.

This was my dream for a very long time but unfortunately, we need to focus on drugs. Glad to see Ben and @A_Aspuru_Guzik explore this space first. Kudos to the luchadores, great paper!
