In case someone is interested about this domain. There was an interesting challenge around it on AIcrowd last year.

It was called 'Learning to Smell' and hosted by popular swiss fragrance and flavour business Firmenich. It contains publicly available dataset, baselines, winner codebases, etc., to play around with.
