[ad_1] Using Intel’s Loihi, a neuromorphic chip, the team designed an algorithm based on the brain’s olfactory circuit. When you take a whiff of something, molecules stimulate olfactory cells in your nose. Those cells send signals to the brain’s olfactory system, which then fires off electrical pulses. The researchers were able to mimic that circuitry […]

Google researchers taught an AI to recognize smells
[ad_1] The researchers created a data set of nearly 5,000 molecules identified by perfumers, who labeled the molecules with descriptions ranging from “buttery” to “tropical” and “weedy.” The team used about two-thirds of the data set to train its AI (a graph neural network or GNN) to associate molecules with the descriptors they often receive. […]
Science has brought back the scent of a long-dead flower
[ad_1] For a moment, though, London’s iconic Barbican center will let you smell a fragment of our lost history. In the corner of a new AI exhibit, a cuboid hood dangles from the ceiling. Inside are four nozzles that slowly release carefully-chosen fragrances into the air around you. Bark. Pine. Mint. I’m no smell expert, […]
