While we’re not yet close to replicating the complexity and the intricacy of the human brain with anything artificial, scientists are making progress with certain dedicated devices – like a newly developed programmable resistor. Resistors can be used to make up analog neural networks in artificial intelligence systems, based on a structure designed to mimic
