New page

The '''area under the ROC curve''' ('''AUC''') is a measure for ranking quality.
The best possible value is 1, and any ranking that makes sense would have an AUC > 0.5.
AUC does not give a higher weight to items higher up in the ranking.

 In [[recommender systems]], we are often interested in how well method can rank a given set of [[item]]s.
 The best possible value is 1, and any non-random ranking that makes sense would have an AUC > 0.5.
 AUC does not give a higher weight to items higher up in the ranking.
