guess my days of hand-coded machine learning are coming to an end.
the dev time is too long, low hanging fruits are taken and i feel like living in the stone ages. need to explore open source ml tools and try to use them in our stack, without rendering the whole thing unmaintainable.
sadly, ml tools in cpp are not slam dunk as in java (mahout, weka) or python (nltk, scikit).
btw thanks to Mikio L. Braun et al for maintaining http://mloss.org/software/
