No, not a typo but a play on words.
AI is being used by the perfume industry to bring new combinations of scents together but it can’t smell a thing!
The algo learns from those with a nose for these things, what combinations of raw ingredients and in what quantity, go together to form a marketable perfume. It then goes on to try and find new combinations from up to 1,500 ingredients. These can be tried and accepted or disgarded by perfumers in seconds.
Every success or failure adds to the learning of the algo.
The Iconoclast here wonders if the failures would find a market in the gas industry? After all, many gases are tainted with an unpleasant odour to make them recognisable.
