How Can We Be So Dense? The Benefits of Using Highly Sparse Representations

that was perfect. Thank you very much for your kindness.
would you mind explain about the paper “how can we be so dense papers 'code” , what is the output of spatial pooling in this code ?

I run this code (how can we be so dense papers 'code) 2 days ago but it is not finished yet.I want to know why does it take so long ?what should I do to run this code faster?
