Silver Nanowire Networks to Overdrive AI Acceleration, Reservoir Computing

Nov 07, 2023 - tomshardware.com
Researchers from the Universities of California and Sydney have developed a silver nanowire-based approach to reduce the power consumption of artificial neural networks. The silver nanowire networks (NWNs) have a neural network-like physical structure and memristive elements, allowing them to change their pattern in response to a stimulus and maintain that pattern when the stimulus is gone. This makes them suitable for use as computing devices. The researchers' silver NWN demonstrated the ability to sequence memory recall tasks against a benchmark image recognition task with an overall accuracy of 93.4%.

The NWNs also have the capability for continuous, dynamic training, allowing the network to learn without having to be trained and retrained on the same data. This could potentially eliminate the need for hyper-parametrization and enable adaptive, gradual change of their knowledge space. The researchers believe that the use of neuromorphic nanowire networks could lead to significant improvements in energy efficiency in AI processing tasks. This is the first reported instance of a Nanowire Network being experimentally run against an established machine learning benchmark, indicating a promising future for this technology.

Key takeaways:

  • Researchers from the Universities of California and Sydney have developed a silver nanowire-based approach to reduce the power consumption of artificial neural networks.
  • The nanowire networks (NWNs) possess a neural network-like physical structure and exhibit brain-like collective dynamics, which can be used as computing devices.
  • The silver NWNs can continuously learn and adapt with each new piece of data, eliminating the need for repeated training on the same data.
  • The use of neuromorphic nanowire networks could significantly improve energy efficiency in AI processing tasks, a key advantage over existing AI acceleration solutions.
