Bayesian Games for Adversarial Regression Problems
We study regression problems in which an adversary can exercise some control over the data generation process. Learner and adversary have conflicting but not necessarily perfectly antagonistic objectives. We study the case in which the learner is not fully informed about the adversary’s objective; instead, any knowledge of the learner about parameters of the adversary’s goal may be reflected in...
متن کاملA Regression Approach for Modeling Games with Many Symmetric Players
We exploit player symmetry to formulate the representation of large normal-form games as a regression task. This formulation allows arbitrary regression methods to be employed in in estimating utility functions from a small subset of the game’s outcomes. We demonstrate the applicability both neural networks and Gaussian process regression, but focus on the latter. Once utility functions are lea...
متن کاملBayesian Games for Adversarial Regression Problems (Online Appendix)
The matrix φ(cd) diag (cl)φ(cd) and hence the expectation ∫ φ(cd) diag (cl)φ(cd)dq(cd) is positive semidefinite for any adversary’s strategy φ(cd). Thus, all eigenvalues λi ≥ 0 are non-negative. The corresponding eigenvectors are additionally eigenvectors of Im + ∫ φ(cd) diag (cl)φ(cd)dq(cd) with eigenvalues 1 + λi > 0. Thus, the inverse matrix exists independently of the choice of φ. This prov...
متن کاملCournot games with linear regression expectations in oligopolistic markets
In this paper, a Cournot game in an oligopolistic market with incomplete information is considered. The market consists of some producers that compete for getting higher payoffs. For optimal decision making, each player needs to estimate its rivals’ behaviors. This estimation is carried out using linear regression and recursive weighted least-squares method. As the information of each player ab...
متن کاملUsing games in Oncology Teaching
Introduction:Educational methods can be classified into two groups: active methods and passive ones. Applying games is an active approach in teaching. The present study aimed at investigating the effect of games on teaching oncology. Methods: Twenty three medical students participated in the study. They took two class sessions of oncology. In the first session the basic principles and concepts...
