SpecNet: Spectral Domain Convolutional Neural Network

  title={SpecNet: Spectral Domain Convolutional Neural Network},
  author={Bochen Guan and Jinnian Zhang and William A. Sethares and Richard Kijowski and Fang Liu},
The memory consumption of most Convolutional Neural Network (CNN) architectures grows rapidly with increasing depth of the network, which is a major constraint for efficient network training and inference on modern GPUs with yet limited memory. [...] Key Method SpecNet exploits a configurable threshold to force small values in the feature maps to zero, allowing the feature maps to be stored sparsely.Expand
