Template class SparseMatrix is in namespace SparseMatrix.
So for all SparseMatrix referred in criteo_latency.cpp, they should be revised to SparseMatrix::SparseMatrix, or using namespace SparseMatrix.

Also, the function cnt_time is not available, because of the failure of static type casting.
The error can be eliminated if revise this function to

template <typename T>
double cnt_time(T start, T end) {
    auto diff = end - start;
    return chrono::duration <double, milli>(diff).count();
}

.

Hi, Riley, thanks for pointing out this issue. Since this link has not been updated for quite a while, I will leave your suggestion here to let others know.

Thanks a lot again.
