multi-armed bandit algorithms算法 Bandit算法是一类强化学习算法，用于解决类似于多臂老虎机（multi-armed bandit）的问题。在多臂老虎机问题中，一个代理需要在有限时间内选择多个臂（arm）中的一个，每个臂都有一个未知的概率分布，代理的目标是最大化其收益。 Bandit算法的核心思想是在代理探索（explore）和利用（...
We consider the classical multi-armed bandit problem with Markovian rewards. When played an arm changes its state in a Markovian fashion while it remains frozen when not played. The player receives a state-dependent reward each time it plays an arm. The

这篇论文的setting 很奇特,最开始没看实验的时候会觉得 setting 挺不可思议的. 论文假设有一个 bandit, 并且用户可以同时拉多个 arm,有的 arm 收益为正有的收益为负,需要找到最优的方案使得用户收益最大. 所以拉多少个也是需要考虑的问题. 到这里并没有把 setting 完全讲清楚,所以看起来非常奇怪,他们要研究的...
作者提出使用maximum entropy semi-supervised criterion,它可以利用未标注的样本,其次我们将我们的问题看做是一个multi-armed bandit problem,其中每一个专家对应于一个slot machine并且在每次试验中我们被允许play one machine(这也就是说,选择一个Active-learning algorithm来产生下一个query)。我们然后使用一个已知的...
multiarmed bandit原本是从赌场中的多臂老虎机的场景中提取出来的数学模型。 是无状态(无记忆)的reinforcement learning。目前应用在operation research,机器人,网站优化等领域。arm:指的是老虎机 (slot machine)的拉杆。bandit:多个拉杆的集合,bandit = {arm1, arm2.. armn}。每个bandit setting对应一个回报函数(...
We also relate to the study of fairness in bandit problems. While Joseph et al. (2016) considers fairness (which is a finite-time variant of our notion of risk neutrality) as a constraint for algorithm design and constructs algorithms that approximately satisfy it, this paper provides evidence...
The pseudo code for sampling a process version (or “arm” in multi-armed bandit terminology) to test its performance is shown in Algorithm 1. The algorithm maintains an average of complete, incomplete, and overall rewards for eachd-dimensional context in relevant matrices, indicated asb. These...
