Abstract
Techniques for noise and bound management for DNN training on RPU crossbar arrays using a scaling factor based on a worst-case scenario are provided. In one aspect, a method for noise and bound management includes: obtaining input vector values x for an analog crossbar array of RPU devices, wherein a weight matrix is mapped to the analog crossbar array of RPU devices; and scaling the input vector values x based on a worst-case scenario to provide scaled input vector values x' to use as input to the analog crossbar array of RPU devices, wherein the worst-case scenario includes an assumed maximal weight of the weight matrix multiplied by a sum of absolute values from the input vector values x.
