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…
Adversarial bandit optimization for approximately linear functions
Zhuoyu Cheng, Kohei Hatano, Eiji Takimoto
We consider a bandit optimization problem for nonconvex and non-smooth functions, where in each trial the loss function is the sum of a linear function and a small but arbitrary pe…
Multi-thresholding Good Arm Identification with Bandit Feedback
Xuanke Jiang, Sherief Hashima, Kohei Hatano +1
We consider a good arm identification problem in a stochastic bandit setting with multi-objectives, where each arm is associated with a distribution defined over…
