The winner takes it all
Nanowire networks are promising for providing a low-energy solution to storing and processing large amounts of data on brain-inspired computer chips.
Memristors are resistors that can simultaneously store and process data. Networks of metal nanowires could be used to make memristors for artificial intelligence (AI).
A team that included researchers from University College Cork in Ireland made a random network of silver nanowires connected by junctions, similar to the way neurons are connected by synapses in the brain. They then tweaked the network until a ‘winner-takes-all’ pathway emerged, such that all the stored memory became restricted to a single connectivity pathway that required the least energy to create.
Improvements to brain-inspired computing are gradually paving the way for AI with increasing levels of seemingly natural intelligence.
