Classifying Russian Speech Commands with a Hardware-Deployable Spiking Neural Network Transferred from an Artificial Neural Network
摘要
We present a baseline accuracy of classifying audio recordings of command words in Russian from a recent dataset RuSC using a three-layer convolutional spiking neural network of integrate-and-fire neurons. The network is obtained by transferring weights from a trained network of ReLU neurons of same topology, and then by adjusting neuron thresholds using a same-topology network with the ClipFloor activation function. In order to make the network prospectively deployable to neuromorphic processors, its synaptic weights are quantized to 8-bit integer. When the duration of presenting one input sample is 200 time steps of spiking network, the resulting performance is the f1-micro of 98
