ODORS; SMELL; SINGLE molecules; MOLECULAR structure

"Our bandwidth for profiling molecules is orders of magnitude faster", says Michigan State University food scientist Emily Mayhew, who co-led the study. In the new study, the researchers trained a neural network with 5,000 known odorants to emphasize 256 chemical features according to how much they affect a molecule's odor. Principal Odor Map Scientists assembled a data set of about 5,000 molecules, each described by various odor "labels" and structural features, resulting in a principal odor map encompassing 256 dimensions.
