Large-Scale Top-N Recommendation with Minimum Item Coverage: Prediction Score Matrices

This dataset contains the derived user-item prediction score matrices used in the experiments of “Large-Scale Top-N Recommendation with Minimum Item Coverage: A Network-Flow Reformulation and Specialized Algorithms.” The matrices were generated with LETTER from publicly available Amazon 5-core review data and the Yelp Open Dataset. They are provided solely to reproduce the reported optimization experiments. The accompanying code, processed-result artifacts, and instructions are available at https://github.com/qxhuang-123/large-scale-top-n-minimum-coverage. Original source-data terms remain applicable.
