“Artificial synapses” can make the nervous system work more like the brains

Resistors that work in a similar way to the body’s nerve cells can be used to build neural networks for machine learning. Many machine learning models rely on increased processing power to achieve results, but this has high energy costs and generates large amounts of heat. One proposed solution is an analog learning machine that … Read more
