We propose a stochastic control approach to the dynamic maximization of robust utility functionals that are defined in … terms of logarithmic utility and a dynamically consistent convex risk measure. The underlying market is modeled by a … incomplete. Our main results give conditions on the minimal penalty function of the robust utility functional under which the …

theory with personalized recommendation, and explicitly considers product relationships. It describes and predicts utility of … utility of one product may depend on whether or not other products are purchased. For example, the utility of a camera lens is … much higher if the user has the appropriate camera (complements), and the utility of one camera is lower if the user …
