Subset Searching Algorithm Using DPP Greedy MAP

CRAN Package

Given item set, item representation vector, and item ratings, find a subset with better relevance-diversity trade-off. Also provide machine learning algorithm to learn item representations maximizing log likelihood under DPP assumption.
