In this setting, the adoption of semantics-aware representations can be very useful to build a more precise representation of users and items, and, in turn, to generate better recommendations. To this end, this chap

Recently, recommender systems have been shown vulnerable to adversarial attacks that force the models to produce misleading recommendations. For instance, adversaries can attempt to push target items into high/low positions in the recommendation lists by inserting optimized fake profiles in

A first step towards selecting an appropriate algorithm is to decide which properties of the application to focus upon when making this choice. Indeed, recommender systems have a var
