resource allocation techniques have recently appeared as a widely recognized feature in lte networks. most of existing approaches in resource allocation focus on maximizing network’s utility functions. the great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (mos) indexes has attracted large efforts over the last few years. in this p...

Current conversational recommender systems do not offer guarantees on the quality of their recommendations, either because they do not maintain a model of a user’s utility function, or do so in an ad hoc fashion. In this paper, we propose an approach to recommender systems that incorporates explicit utility models into the recommendation process in a decision-theoretically sound fashion. The sy...

(ABSTRACT) In this proposal, we consider scheduling distributed soft real-time tasks in unreliable (e.g., those with arbitrary node and network failures) and untrustworthy systems (e.g., those with Byzantine node behaviors). We present a distributed real-time scheduling algorithm called Real-Time Gossip (or RTG). RTG considers a distributed (i.e., multi-node) task model where tasks are subject ...

An interesting approach for designing scheduling algorithms in OFDMA systems consists on incorporating a utility function that maps a certain resource or performance criterion into a value that measures the degree of user satisfaction. The current paper proposes a utility function that maps the user data rate into the quality of experience (QoE) perceived by the end user. The utility function i...

This article builds on the mean-variance criterion and the links with the expected utility maximization to define the optimal allocation of portfolios, and extends the results in two ways, first considers tailored made utility functions, which can be non continuous and able to capture possible preferences associated with some portfolio managers. Second, it presents results that relate to static...
