  "Description": "Calculates evaluation metrics for implicit-feedback\nrecommender systems that are based on low-rank matrix\nfactorization models, given the fitted model matrices and data,\nthus allowing to compare models from a variety of libraries.\nMetrics include P@K (precision-at-k, for top-K\nrecommendations), R@K (recall at k), AP@K (average precision at\nk), NDCG@K (normalized discounted cumulative gain at k), Hit@K\n(from which the 'Hit Rate' is calculated), RR@K (reciprocal\nrank at k, from which the 'MRR' or 'mean reciprocal rank' is\ncalculated), ROC-AUC (area under the receiver-operating\ncharacteristic curve), and PR-AUC (area under the\nprecision-recall curve). These are calculated on a per-user\nbasis according to the ranking of items induced by the model,\nusing efficient multi-threaded routines. Also provides\nfunctions for creating train-test splits for model fitting and\nevaluation.",
