Training neural hardware with noisy components

Proceedings of the International Joint Conference on Neural Networks

Rothganger, Fredrick R.; Evans, Brian R.; Aimone, James B.; DeBenedictis, Erik

Some next generation computing devices may consist of resistive memory arranged as a crossbar. Currently, the dominant approach is to use crossbars as the weight matrix of a neural network, and to use learning algorithms that require small incremental weight updates, such as gradient descent (for example Backpropagation). Using real-world measurements, we demonstrate that resistive memory devices are unlikely to support such learning methods. As an alternative, we offer a random search algorithm tailored to the measured characteristics of our devices.
