The model is going to be used to classify a larger collection of documents using an Openscoring open source web service or other technology (on you suggestion). The model should be optimized to provide the best combination of TP ...

    We are in need of a programmer who knows R. An internal projection tool utilizes this language to run a Monte Carlo simulation to give us an idea of what is possible and can be expected for paid search. Because we have the code already in place, and really just need someone with an understanding of R to execute the model, this will likely be a short term engagement (no more than 4 to 5 hours, max). Below are the ...
