Lightweight AI for UAV-Mounted RIS: An Overview
Sherief Hashima, Kohei Hatano, Eiji Takimoto +3
Unmanned Aerial Vehicles (UAV)-mounted Reconfigurable Intelligent Surfaces (RIS) have emerged as a promising architecture for enhancing wireless coverage, spectral efficiency, and…
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…
Online Combinatorial Linear Optimization via a Frank-Wolfe-based Metarounding Algorithm
Ryotaro Mitsuboshi, Kohei Hatano, Eiji Takimoto
Metarounding is an approach to convert an approximation algorithm for linear optimization over some combinatorial classes to an online linear optimization algorithm for the same cl…
