Researchers Develop AI ‘Nose’

Saturday, August 12, 2017 - 12:23

Russian researchers have developed an electronic "nose" which can remember new smells and recognize them after the event.

An AI takes over and checks a smell it detected, against a database of known scents for "the closest similar smell determined by the smallest Hamming distance to any know code," HSE writes. If it can't find a match, the sensor will identify the scent as being new.

The difference between this and other scent prediction/identification tech is that it can sense more than one scent at a time. Useful for, say, gas mixtures.

"Essentially, we want to teach the device to discriminate between hazardous and non-hazardous gas mixtures and memorize them fast," MIEM HSE professor Vladimir Kulagin says.
