Google Artificial Intelligence-A team of Google researchers says they’ve taught an artificial intelligence how to smell.
In a paper published in Arxiv, researchers from Google’s Brain Team describe how they used machine-learning to instruct a robot to accurately categorize different smells by assessing their molecular structure.
The bot was trained using a database of 5,000 molecules which have been identified and labeled by perfume makers with different descriptors like ‘pungent’ or ‘grassy.’
Researchers fed two-thirds of the database into the bot’s neural network and then used the remaining unfamiliar scents to test the AI on those it hadn’t analyzed – it passed.
Researchers have long attempted to program a sense of smell using artificial intelligence, but several hurdles have proved difficult to surmount.
