The inplementation of Convolutional

Optimizing Conv in Caffe

  • Solution: converting Conv to GEMM
    This is done in two lasy steps:
    (1) do an im2col to convert the image to a matrix
    (2) call GEMM to do the actual computation
  • Pros:
    simple logic, easy implementation
  • Cons:
    Lots of memory overhead
