چکیده

We investigate robust decision-making under utility uncertainty, using the maximin criterion, which optimizes utility for the worst case setting. We show how it is possible to efficiently compute the maximin optimal recommendation in face of utility uncertainty, even in large configuration spaces. We then introduce a new decision criterion, setwise maximin utility (SMMU), for constructing optimal recommendation sets: we develop algorithms for computing SMMU, and prove (analogously to previous results related to regret-based and Bayesian elicitation) that SMMU determines choice sets for queries that are myopically optimal. We also present experimental results showing performance of SMMU on randomly generated elicitation problems.

Regret-Based Optimization and Preference Elicitation for Stackelberg Security Games with Uncertainty

Stackelberg security games (SSGs) have been deployed in a number of real-world domains. One key challenge in these applications is the assessment of attacker payoffs, which may not be perfectly known. Previous work has studied SSGs with uncertain payoffs modeled by interval uncertainty and provided maximin-based robust solutions. In contrast, in this work we propose the use of the less conserva...

Regret-based Incremental Partial Revelation Mechanisms

Classic direct mechanisms suffer from the drawback of requiring full type (or utility function) revelation from participating agents. In complex settings with multi-attribute utility, assessing utility functions can be very difficult, a problem addressed by recent work on preference elicitation. In this work we propose a framework for incremental, partial revelation mechanisms and study the use...

Regret-based Utility Elicitation in Constraint-based Decision Problems

Constraint-based optimization requires the formulation of a precise objective function. However, in many circumstances, the objective is to maximize the utility of a specific user among the space of feasible configurations (e.g., of some system or product). Since elicitation of utility functions is known to be difficult, we consider the problem of incremental utility elicitation in constraintba...

Constraint-based optimization and utility elicitation using the minimax decision criterion

In many situations, a set of hard constraints encodes the feasible configurations of some system or product over which multiple users have distinct preferences. However, making suitable decisions requires that the preferences of a specific user for different configurations be articulated or elicited, something generally acknowledged to be onerous. We address two problems associated with prefere...
