Not long ago (this year, actually), with Sherry we wrote a book Chapter on recommender systems focusing on sources of knowledge and evaluation metrics. In section 7.4 we explain MAP: Mean Average Precision. Providing sound way-finding support for lifelong learners in Learning Networks requires dedicated personalised recommender systems (PRS), that offer the learners customised advise on which learning actions or programs to study next. 1.1: Learning Networks (LN) can facilitate self-organized, learner-centred lifelong learning. We also illustrate specific computational models that have been proposed for mobile recommender systems and we close the paper by presenting some possible future developments and extension in this area. Introduction: Recognition of human behavior and human creation is a very powerful tool. An attack against a collaborative filtering recommender system consists of a set of attack profiles, each contained biased rating data associated with a fictitious user identity, and including a target item, the item that the attacker wishes that item- based collaborative filtering might provide significant robustness compared to the user-based algorithm, but, as this paper shows, the item-based algorithm also is still vulnerable in the face of some of the attacks we introduced. Following the post on evaluation metrics in your blog, we would be glad to help you testing new evaluation metrics for GraphChi. 1- A moderator decides on what products to sell in the package, 2- You build a smart recommendation system that can do this job for the moderator. LN consist of participants and learning actions that are related to a certain domain (Koper and Sloep 2002). For these two options, smart mechanisms like the ones used for personalization are Thanks to this, products that are normally not advertised because of their unpopularity are introduced to buyers that might buy those products.

The Recommender Stammtisch is a meetup for people who are interested in recommender systems, user behavior analytics, machine learning, AI and related topics.
