Machine olfaction needs machine learning.
ArticleBody:This article was originally featured on The Conversation. Over 100 years ago, Alexander Graham Bell asked the readers of National Geographic to do something bold and fresh – “to found a new science.” He pointed out that sciences based on the measurements of sound and light already existed. But there was no science of odor. Bell asked his readers to “measure a smell.
The competition released data collected by Andreas Keller and Leslie Vosshall, biologists who study olfaction, and invited teams from around the world to submit their machine learning models. The models had to predict odor labels like “sweet,” “flower” or “fruit” for odor-causing compounds based on their molecular structure. The top performing models were published in a paper in the journal Science in 2017.
