Over 5000 molecules from two different flavor and scent data sets were used to create a map.
In the neural model, over 5000 molecules from two different flavor and scent data sets were used. By asking it to describe how 320 distinct compounds would smell based on their structures and contrasting this with descriptions of smell from a group of 15 individuals, Mainland and his colleagues evaluated the system's performance.
In addition, in a separate study, Mainland's colleagues used the neural network to create a map connecting the molecular structures of compounds that repelThis allowed the researchers to identify molecules that, according to the model, would be at least as repellent as leading anti-mosquito products and could be tested in future trials.
Joel Mainland also acknowledges this and says future work will focus on producing models that can identify enantiomers and more complex mixtures of molecules rather than just the single molecules the current model works with.Mapping molecular structure to odor perception is a key challenge in olfaction. Here, we use graph neural networks to generate a Principal Odor Map that preserves perceptual relationships and enables odor quality prediction for novel odorants.
