However, the cost to access some of these services is surprisingly high. Training and running AI models are hugely expensive, but new research from the University of Sydney and the University of California points to a potentially cheaper way. The researchers created a rat’s nest of silver nanowires that could prove to be a much more efficient way to run neural networks.Today’s prominent AI systems like ChatGPT run on massage banks of AI accelerators, essentially GPUs with a ton of VRAM and no video output. The hardware is hugely expensive (you’d be lucky to find a single Nvidia H100 for $30,000), and the power to keep them running is a significant ongoing cost. The nanotechnology approach devised by the researchers has the potential to be much more efficient.Using advanced nanotech fabrication, the team created networks of silver nanowires, each strand about one-thousandth the width of a human hair. The wires are arranged randomly, forming a network where the strands cross and interact like the synapses in a brain. This is a type of neuromorphic computing, which means the wires behave like a physical neural network—it’s a hardware network instead of a software one.According to the study published in Nature Communications, the nanowires display brain-like behavior when electrical signals pass through the network. The thousands of intersections between wires undergo signal changes in response to electrical impulses, and that response happens in real time. Thus, the team says nanowire networks are ideal for online machine learning.With online learning, you don’t need to bundle data into large batches, which is why AI accelerators have tens of gigabytes of RAM. Feeding data as a continuous stream is simply more efficient. Even at this early stage, this approach works for some core machine-learning activities. The team converted the MNIST handwritten data set to electrical signals and it into their hardware network, which was able to learn how to identify written numbers. They also tested memory-like tasks of recalling numbers, and the model could do that.It will take a while before nanowire networks can compete with high-power AI accelerators, but there could be applications that don’t need all that power. The team believes there’s still much to learn about neuromorphic networks.Source LinkYouTube Teases AI-Powered Creator ToolsAsus Launches Cheaper ROG Ally With AMD Ryzen Z1 ChipMassive Cosmic Explosion Forms 300 Earths’ Worth of Rare Heavy MetalsApple Is Planning a ‘Secretive’ Vision Pro Training Event in CupertinoIntel Announces Thunderbolt 5 at Up to 120Gb/s'Solar Leaf' Concept Said to Harvest 13% More Sun Than Standard Solar CellsKingston Nabbed 78% of Global DRAM Module Market in 2022China Bans iPhones for Some Workers, Citing Security RiskShare the Tech Knowledge!
