Phys.org  April 21, 2023 In their previous work an international team of researchers (Australia, Japan, USA – NIST) showed how nanotechnology could be used to build a brain-inspired electrical device with neural network-like circuitry and synapse-like signaling. Their current work paves the way towards replicating brain-like learning and memory in non-biological hardware systems and suggests that the underlying nature of brain-like intelligence may be physical. They implemented task variations inspired by the n-back task (a common memory task used in human psychology experiments) in a nanowire network (NWN) device and applied external feedback to emulate brain-like supervised and reinforcement learning.
