Sep 9, 2020 · The choice of a given rank metric is important because studies sometimes find differences in the ability of different rank metrics to predict rank-related traits, even in the same population. For example, Archie et al. [ 26 ] demonstrated that proportional rank, but not simple ordinal rank, predicted risk of injury in female baboons in the Amboseli ecosystem in Kenya [ 26 ].

two dominance rank metrics —simple ordinal rank and proportional or ‘stan-dardized’ rank—to predict 20 traits in a wild baboon population in Amboseli, Kenya. We propose that simple ordinal rank best predicts traits when compe-tition is density-dependent, whereas proportional rank best predicts traits when competition is density-independent.

To evaluate recommendations, you must have predictions as user-item pairs, the binary or graded relevance score as the ground truth, and choose the K parameter. The K parameter sets the cutoff point for the top recommendations you evaluate. You can use predictive metrics like accuracy or Precision at K or ranking metrics like NDCG, MRR, or MAP ...
Jul 2, 2015 · 36. I'm interested in looking at several different metrics for ranking algorithms - there are a few listed on the Learning to Rank wikipedia page, including: • Mean average precision (MAP); • DCG and NDCG; • Precision@n, NDCG@n, where "@n" denotes that the metrics are evaluated only on top n documents; • Mean reciprocal rank;
Nov 25, 2019 · They operate at the individual rating prediction level. If a user rated an item with 4.5 these metrics tell us how far-off are our predictions if we predicted a rating of 1.2 or 4.3. Decision ...
