Adversarial Bandit Optimization with Globally Bounded Perturbations to Convex Losses
Zhuoyu Cheng, Kohei Hatano, Eiji Takimoto
We study adversarial bandit optimization in which the loss functions may be non-convex and non-smooth. In each round, the learner selects an action and observes only the loss incur…

Adversarial Bandit Optimization with Globally Bounded Perturbations to Linear Losses
Zhuoyu Cheng, Kohei Hatano, Eiji Takimoto
We study a class of adversarial bandit optimization problems in which the loss functions may be non-convex and non-smooth. In each round, the learner observes a loss that consists…
