Bandit Algorithms —— 1.1 Introduction 这段时间为了给自己的application工作画一个完美的句点,在bandit方向上挣扎了很久。目前是处于Empirical study已经做到SOTA了,但是theoretical analysis还没做完,甚至有点捉襟见肘。顿时深感知识容量还不足,因此紧锣密鼓地开始看了书籍,这里
His research is focused on decision making in the face of uncertainty, including bandit algorithms and reinforcement learning. Before joining DeepMind he was an assistant professor at Indiana University and a postdoctoral fellow at the University of Alberta. Csaba Szepesvári is a Professor in the ...
Genetic algorithmsReinforcement learningMulti-armed bandit tasks have been extensively used to model the problem of balancing exploitation and exploration. A most challenging variant of the MABP is the non-stationary bandit problem where the agent is faced with the increased complexity of detecting ...
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(r...

4. UCB1 (Bandit Algorithms Continued)方法 我们发现上面两个方法中,某个拉杆预估的中奖概率是随着这个拉杆被拉动的次数而变化的。我们是通过预估概率作为评判标准,来决定去拉哪一个拉杆。 如果一个拉杆没有被拉到,那么这个拉杆的预估中奖概率就不会改变。然而通过直觉就可以理解,一个拉杆的预估概率的准确度是跟你...

Here’s where it gets particularly interesting: while intuitively one might think the task of our Multi-armed Bandit algorithms is to unearth that ideal price where the probability of purchase is highest, it’s not quite so straightforward. In fact, our ultimate goal is to maximize the reven...
