1. A computer-implemented method, comprising: identifying filter reduction ratios for a plurality of filters, each respective filter reduction ratio corresponding to a respective reduction of training assets based on use of a respective filter; receiving a requested reduction ratio; and selecting, by a computing system, a subset of filters from the plurality of filters based at least in part on the requested reduction ratio and the filter reduction ratios, the subset of filters selected such that applying the subset of filters to a set of a number of media assets reduces the number of media assets in the set according to the requested reduction ratio.
