AI Hardware Design Could Filter Out Irrelevant Visual Data to Reduce Energy Use

NUS researchers built a molybdenum disulfide transistor that can act as a logic filter, a neuron or a synapse, and used it to block irrelevant visual data before a spiking neural network processes it. In simulations, cropping digits cut active hardware tiles by about 36% for a 0.3-point accuracy loss, and a traffic scene used about 59% less energy for vehicle recognition and 77% less for licence plates. We explain how it works, check the arithmetic and list what the press release leaves out.

Toward Physical AI: When the Hardware Becomes the Neural Network

On 18 September 2026 Nature Reviews Physics published a 165-reference Perspective arguing that self-organising memristive networks can learn physically, with no separation between the model and the hardware running it. Six researchers from Los Alamos, INRiM Turin, UCLA, Politecnico di Torino, the University of Canterbury and the University of Sydney set out what has been measured: 93.4% on MNIST learned online on a nanowire device, reservoir computing that trains only a readout layer, and criticality as a tuning target. This piece separates the measured results from the ambition, sets the energy argument against the IEA’s data-centre projections, and lists the four open problems — variability, drift, scaling and readout — that stand between a review paper and a component you can buy.
