> Currently SINGA uses [Mshadow|https://github.com/dmlc/mshadow/tree/master/doc]'s unpatch2col
and pool expression in the implementation of convolution and pooling layer. After comparing
them with Caffe's implementation using im2col and pooling implementation, we found the later
implementation is faster. Hence we can add them into SINGA as two new layers, CaffeConvLayer
and CaffePoolingLayer.
