This set of scripts will be use to construct a framework for experiments on Recommender Systems. The purpose of these experiments is to determine how sampling user ratings that are cached by the RS system affects system accuracy and item coverage. This class compute the inverse user freqency for each item and assigns each user an average IUF value that it loads into our database.
