1、A Problem in which a fixed limited set of resources must be allocated between competing (alternative) choices in a way that maximizes their expected gain, when each choice's properties are only partially known at the time of allocation, and may become better understood as time passes or by...
这就是多臂赌博机问题 (Multi-armed bandit problem, K-armed bandit problem, MAB)。最简单的去试,有策略地快速试就是bandit算法。 3.数学表述 ·设共有k个手柄 ·k个手柄的汇报分布是D1,D2,...,Dk ·回报均值u1,u2,...,uk ·最佳手柄收益 u* = max{ui},i=1,...k ·T轮之后的regret值,使用...
多臂老虎机算法(Multi-Armed Bandit, MAB)是一种用于解决探索与利用(exploration-exploitation)问题的算法框架。在这种场景中,一个玩家面对多个老虎机(或称为臂),每个老虎机都有一个未知的奖励概率分布。玩家的目标是通过一系列选择来最大化长期累积的奖励。一、基本概念 奖励:每次玩家选择一个老虎机并拉下它...
可以通过引入多臂老虎机(Multi-Armed Bandit, MAB)算法来提高5G连接态切换的效率。多臂老虎机(Multi-Armed Bandit, MAB)算法属于强化学习中的探索与利用(Exploration and Exploitation)问题。假设现在有 K 台老虎机或者一个 K 根拉杆的老虎机,每台老虎机都对应着一个奖励概率分布,我们希望在未知奖励概率分布的情况...
A multi-armed bandit (MAB) problem is described as follows. At each time-step, a decision-maker selects one arm from a finite set. A reward is earned from this arm and the state of that arm evolves stochastically. The goal is to determine an arm-pulling policy that maximizes expected ...

This metaphorical scenario underpins the concept of the Multi-armed Bandit (MAB) problem. The objective is to find a strategy that maximizes the rewards over a series of plays. While exploration offers new insights, exploitation leverages the information you already possess. ...
