Block Sparse Kernel

  • For networks with block sparse weights
  • Can choose amount of Sparsity
  • Can replace normal Dense Layers with sparse and wide or sparse and deep
  • Enables wider and deeper networks
  • Only compute on non zero blocks
  • Connectivity is unaffected in the spatial dimensions
  • Compute cost is only prop to number of non zero weights
  • Small World graphs
  • Also useful for compression
