Query: BS4NN: Binarized Spiking Neural Networks with Temporal Coding and
  Learning   We recently proposed the S4NN algorithm, essentially an adaptation of
backpropagation to multilayer spiking neural networks that use simple non-leaky
integrate-and-fire neurons and a form of temporal coding known as
time-to-first-spike coding. With this coding scheme, neurons fire at most once
per stimulus, but the firing order carries information. Here, we introduce
BS4NN, a modification of S4NN in which the synaptic weights are constrained to
be binary (+1 or -1), in order to decrease memory (ideally, one bit per
synapse) and computation footprints. This was done using two sets of weights:
firstly, real-valued weights, updated by gradient descent, and used in the
backward pass of backpropagation, and secondly, their signs, used in the
forward pass. Similar strategies have been used to train (non-spiking)
binarized neural networks. The main difference is that BS4NN operates in the
time domain: spikes are propagated sequentially, and different neurons may
reach their threshold at different times, which increases computational power.
We validated BS4NN on two popular benchmarks, MNIST and Fashion-MNIST, and
obtained reasonable accuracies for this sort of network (97.0% and 87.3%
respectively) with a negligible accuracy drop with respect to real-valued
weights (0.4% and 0.7%, respectively). We also demonstrated that BS4NN
outperforms a simple BNN with the same architectures on those two datasets (by
0.2% and 0.9% respectively), presumably because it leverages the temporal
dimension. The source codes of the proposed BS4NN are publicly available at
https://github.com/SRKH/BS4NN.
