Computers That Smell: Intel’s Neuromorphic Chip Can Sniff Out Hazardous Chemicals

What’s New: In a joint paper published in Nature Machine
Intelligence, researchers from Intel Labs and Cornell University
demonstrated the ability of Intel’s neuromorphic research chip,
Loihi, to learn and recognize hazardous chemicals in the presence
of significant noise and occlusion. Loihi learned each odor with
just a single sample, without disrupting its memory of previously
learned scents. It demonstrated superior recognition accuracy
compared with conventional state-of-the-art methods, including a
deep learning solution that required 3,000 times more training
samples per class to reach the same level of classification
accuracy.

“We are developing neural algorithms on Loihi that mimic what
happens in your brain when you smell something. This work is a
prime example of contemporary research at the crossroads of
neuroscience and artificial intelligence and demonstrates Loihi’s
potential to provide important sensing capabilities that could
benefit various industries.”
–Nabil Imam, senior research scientist in Intel’s Neuromorphic
Computing Lab
About the Research: Using a neural algorithm derived from
the architecture and dynamics of the brain’s olfactory circuits,
researchers from Intel and Cornell trained Intel’s Loihi
neuromorphic research chip to learn and recognize the scents of 10
hazardous chemicals. To do so, the team used a dataset consisting
of the activity of 72 chemical sensors in response to these smells
and configured the circuit diagram of biological olfaction on
Loihi. The chip quickly learned the neural representation of each
of the smells and recognized each odor, even when significantly
occluded, demonstrating a promising future for the intersection of
neuroscience and artificial intelligence.
