Collaborative filtering or recommender systems use a database about user preferences to predict additional topics or products a new user might like. [...] Key Method We use two basic classes of evaluation metrics. The first characterizes accuracy over a set of individual predictions in terms of average absolute deviation. The second estimates the utility of a ranked list of suggested items. This metric uses an estimate of the probability that a user will see a recommendation in an ordered list. Experiments…Expand
