Efficient training algorithms for neural networks based on memristive crossbar circuits

摘要

We have adapted backpropagation algorithm for training multilayer perceptron classifier implemented with memristive crossbar circuits. The proposed training approach takes into account switching dynamics of a particular, though very typical, type of memristive devices and weight update restrictions imposed by crossbar topology. The simulation results show that for crossbar-based multilayer perceptron with one hidden layer of 300 neurons misclassification rate on MNIST benchmark could be as low as 1.47% and 4.06% for batch and stochastic algorithms, respectively, which is comparable to the best reported results for similar neural networks.
