Query: Revisiting Batch Normalization for Training Low-latency Deep Spiking
  Neural Networks from Scratch   Spiking Neural Networks (SNNs) have recently emerged as an alternative to
deep learning owing to sparse, asynchronous and binary event (or spike) driven
processing, that can yield huge energy efficiency benefits on neuromorphic
hardware. However, training high-accuracy and low-latency SNNs from scratch
suffers from non-differentiable nature of a spiking neuron. To address this
training issue in SNNs, we revisit batch normalization and propose a temporal
Batch Normalization Through Time (BNTT) technique. Most prior SNN works till
now have disregarded batch normalization deeming it ineffective for training
temporal SNNs. Different from previous works, our proposed BNTT decouples the
parameters in a BNTT layer along the time axis to capture the temporal dynamics
of spikes. The temporally evolving learnable parameters in BNTT allow a neuron
to control its spike rate through different time-steps, enabling low-latency
and low-energy training from scratch. We conduct experiments on CIFAR-10,
CIFAR-100, Tiny-ImageNet and event-driven DVS-CIFAR10 datasets. BNTT allows us
to train deep SNN architectures from scratch, for the first time, on complex
datasets with just few 25-30 time-steps. We also propose an early exit
algorithm using the distribution of parameters in BNTT to reduce the latency at
inference, that further improves the energy-efficiency.
