Convolution |
The Caffe strategy for convolution is to reduce the problem to matrix-matrix multiplication. This linear algebra computation is highly-tuned in BLAS libraries and efficiently computed on GPU devices.
For more details read Yangqing's Convolution in Caffe: a memo.
As it turns out, this same reduction was independently explored in the context of conv. nets by
