1. 贪心算法（Greedy Algorithm）：总是选择当前已知期望奖励最高的老虎机臂。2. ε-贪心算法（Epsilon-Greedy Algorithm）：大多数时间选择当前已知期望奖励最高的老虎机臂，但以小概率ε随机选择其他老虎机臂进行探索。3. UCB（Upper Confidence Bound）算法：选择具有最高上置信界（即当前估计的期望奖励加上一个信...
。但是在数学领域,这个问题已经被研究过,被称为多臂老虎机问题(Multi-Armed Bandit Problem),也称为顺序资源分配问题(sequential resource allocation problem)。Bandit algorithm被广泛应用于广告推荐系统,源路由和棋类游戏中。 再举个例子, 假设有个老虎机并排放在我们面前,我们首先给它们编号。每一轮我们可以选择一...
For example, personalized recommendations problem can be modelled as a contextual multi-armed bandit problem in reinforcement learning. In this paper, we propose a contextual bandit algorithm which is based on Contexts and the Chosen Number of Arm with Minimal Estimation, namely Con-CNAME in short....

Empirically, algorithms that use this kind of algorithm seem to work quite well: (1) Bootstrap DQN, (2) Bayesian DQN, (3) Double Uncertain Value Networks, (4) UCLS (new algo in this work).Conduct experiments in a continuous variant of the River Swim domain. UCLS and ...
In contrast, multi armed bandit algorithms maximize a given metric (which is conversions of a particular type in VWO’s context). There’s no intermediate stage of interpretation and analysis as the MAB algorithm is adjusting traffic automatically. What this means is that A/B testing is perfect...
In this article, we’ll explore four Multi-armed Bandit algorithms to evaluate their efficacy against a well-defined (though not straightforward) demand curve. We’ll then dissect the primary strengths and limitations of each algorithm and delve into the key metrics that are instrumental in ...
