本文将在多臂老虎机(multi-armed bandit)的场景下,梳理不同算法是如何解决exploration-exploitation tradeoff问题,并在随后进一步阐述如何在deep reinforcement learnin中应用实践. 本文结构如下: Part I: problem definition Part II: different algorithms to address e-e tradeoff. Part III: how we can do explorati...
Exploitation, on the other hand, exploits the agent's current estimated values. It chooses the greedy action to try to get the most reward. But by being greedy with respect to estimated values, may not actually get the most reward(最终总和不一定是最大回报) The estimated values for the othe...
Learning in modern organizations often involves managing a tradeoff between exploration (i.e., knowledge expansion) and exploitation (i.e., knowledge refinement). In this paper, we consider the implications of this tradeoff in the context of learner-controlled training and development. We then ...
探索(Exploration)还是利用(Exploitation)?强化学习如何tradeoff? 深度强化学习实验室 来源:AI科技评论,编译 | bluemin 作者: DeepRL 探索VS 利用,这是强化学习中至关重要的话题。我们希望强化学习中的智能体尽快找到最佳策略。然而,在没有充分探索的情况下就盲目地选择某个策略会带来一定的问题,因为这会导致模型陷入...
the tradeoff between exploration and exploitation. We denote by Z ej the event “phase j performs exploration with expert e,” and let Z j = e Z ej and ¯ Z i0i = E i j=i0+1 Z j = i j=i0+1 p i . Note that ¯ Z i0i denotes the expected number of exploration phases...
It is well known that a suitable and reasonable tradeoff between exploration and exploitation (T: Er& Ei) is crucial for their success, and having a great effect on global optimization performance, e.g., accuracy and convergence speed of those algorithms. But rigid and useful theoretical study...
You could be reading this or you could be writing that long overdue article. The tradeoff is a natural one and it is the foundation of one of the oldest problems in animal evolution: How should an organism choose between exploiting a resource or exploring to find new resources? This problem...

myopic optimization, Bayesian inventory decisions that consider the exploration-exploitation tradeoff can avoid getting stuck in local optima and improve the ... Z Luo,P Guo,Y Wang - 《Manufacturing & Service Operations Management》 被引量: 0发表: 2023年 On Implications of Demand Censoring in the...
In order to tradeoff exploration/exploitation and inspired by cell genetic algorithm a cell-shift crossover operator for evolutionary algorithm (EA) is proposed in this paper. The definition domain is divided into n-dimension cubic sub-domains (cell) and each individual locates at an n-dimensional...
