Multi-Gradient Descent for Multi-Objective Recommender Systems

Boi Faltings, Claudiu-Cristian Musat, Diego Matteo Antognini

Recommender systems need to mirror the complexity of the environment they are applied in. The more we know about what might benefit the user, the more objectives the recommender system has. In addition there may be multiple stakeholders - sellers, buyers, ...
