Very cool to see more C++-based machine learning efforts. The language still needs a good dataframe abstraction (maybe XFrame?), but with matrix algebra provided by Armadillo/Eigen and other long-time machine learning libraries like mlpack, Shogun, Shark (and if you want to include C, Darknet), personally I think the future is bright for machine learning in C++---especially for production and deployment applications.
