Olfactory Label Prediction on aroma-chemical Pairs

The application of deep learning techniques on aroma-chemicals has resulted in models more accurate than human experts at predicting olfactory qualities. However, public research in this domain has been limited to predicting the qualities of single molecules, whereas in industry applications, perfumers and food scientists are often concerned with blends of many odorants. In this paper, we apply both existing and novel approaches to a dataset we gathered consisting of labeled pairs of molecules. We present a publicly available model capable of generating accurate predictions for the non-linear qualities arising from blends of aroma-chemicals.
