> Use Caffe's im2col and pooling implementation to accelerate conv and pooling 
> operations

>                 Key: SINGA-51
>                 URL: https://issues.apache.org/jira/browse/SINGA-51
>             Project: Singa
>          Issue Type: Improvement

> 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.
