1. A computer-implemented method for retrofitting a recommender system to accommodate voluminous data organized into records having dimensions comprising:

  • pre-processing the data by reducing the number of records to provide pre-processed data such that both a predetermined accuracy threshold and a predetermined performance requirement are met;

    wherein reducing the data by the number of records is stopped specifically as a result of meeting a predetermined accuracy threshold, and pre-processing further comprises repeatedly removing a highest-frequency dimension from the data until the predetermined performance requirement is met; and

    , providing the pre-processed data to the recommender system to generate predictions based on a query and the pre-processed data as reduced in pre-processing.
