WaveQ: Gradient-Based Deep Quantization of Neural Networks through Sinusoidal Adaptive Regularization

Elthakeb, Ahmed T., Pilligundla, Prannoy, Mireshghallah, Fatemehsadat et al.

Understand

As deep neural networks make their ways into different domains, their compute efficiency is becoming a first-order constraint.

  • Deep quantization, which reduces the bitwidth of the operations (below 8 bits), offers a unique opportunity as it can reduce both the storage and compute requirements of the network super-linearly.
  • However, if not employed with diligence, this can lead to significant accuracy loss.
  • Due to the strong inter-dependence between layers and exhibiting different characteristics across the same network, choosing an optimal bitwidth per layer granularity is not a straight forward.
