Now IBM researchers Tayfun Gokmen and Yurii Vlasov have described what could be a gamechanger for machine learning — an array of resistive processing units that would use stochastic techniques to dramatically accelerate the backpropagation algorithm, speeding up neural network training by a factor of 30,000. They argue that such an array would be reliable, low in power use, and buildable with current CMOS fabrication technology.
