Your Policy Regularizer is Secretly an Adversary

Policy regularization methods such as maximum entropy regularization are widely used in reinforcement learning to improve the robustness of a learned policy. ...
In this paper, we show how this robustness arises from hedging against worst-case perturbations of the reward function, which are chosen from a limited set by an imagined adversary. ...
Each policy implicitly hedges against an adversary that perturbs the rewards according to the values and colormap shown. ...

The policy challenge is increasingly moving from identifying who is behind a cyber intrusion to finding the adequate policy response, including whether to publicly attribute. ...
Third, such norm shaping has the potential to exert an independent—though limited—deterrent effect, particularly on potential adversaries. ...
In some of the cases observed, all with developed national security policy capabilities, attribution is normalized and folded into the regular national security policy processes demonstrating that at the ...

It is not an entirely new idea: physicians from ancient times have recognized that medical treatment needs to consider individual variations in patient characteristics. ...
In an adversarial bandit problem, the adversary secretly chooses reward vectors r := {r t } T t=1 where r t ∈ [0, 1] K corresponds to the rewards over all actions at time t. ...

An important contribution of this work is that we carefully formulate the conditions under which policy evaluation using SMC does not lead to the leakage of information about the protection states of the ...
We also study the computational problem of statically checking if an access control policy can be evaluated without information leakage. Lastly, we identify useful policy idioms. Definition 8. ...
This approach employs regular SMC rather than PFE. At the centre of the approach is the static analysis of the shared access policies to detect if they are safe. ...
