Deep Memristive Cellular Neural Networks for Image Classification

We present simulation results of a deep cellular neural network leveraging memristive dynamics to classify images from standard datasets. We have investigated the use of both volatile (NbO2-Mott) and non-volatile (TaOx) memristive devices as output nonlinearity in neural networks. We simulated deep neural networks using these devices and compared their image classification accuracies on commonly investigated datasets to traditional convolutional and cellular architectures of similar complexity. Our results reveal that the exploitation of memristive dynamics in cellular structures can increase classification accuracy by more than 2.5 percent as compared to the traditional convolutional implementations.
