Abstract
A system can compensate for activation drift in analog memory-based artificial neural networks. A set of input activation vectors can be input, at a first point in time, to a crossbar array. The first set of output activation vectors can be read from the output lines of the crossbar array. At a second point in time, which is a later time than the first point in time, the input set of activation vectors can be input to the crossbar array. A second set of output activation vectors can be read from the crossbar array. A function that maps the second set of output activation vectors to the first set of output activation vectors can be determined. The function can be applied to subsequent output activation vectors output by the crossbar array. A method thereof, can also be provided.
