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 ...
exploration exploitation tradeoff 星晴 Attention is all you need 1 人赞同了该文章 当我们身处一个非完备信息的环境(environment with incomplete information)做决策时,常常会陷入这样一个困境:是基于[当前已经获取的信息所得到的]当前最优策略行动,获得一个即时较高的回报(exploitation), 还是采取一个当前来看是次...
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...
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...
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...
In this paper, we propose a novel survival analysis method to intelligently guide the maintenance of the exploration-exploitation tradeoff in multiobjective evolutionary algorithms. The survival analysis stems from a deep understanding of the evolutionary search procedure. Through survival analysis, an ...
What is the exploration-exploitation tradeoff? The exploration-exploitation trade-off isa fundamental dilemma whenever you learn about the world by trying things out. The dilemma is between choosing what you know and getting something close to what you expect ('exploitation') and choosing something ...
Whether to continue to exploit a source of reward, or to search for a new one of potentially greater value, is a fundamental and underconstrained decision. Recent computational studies of this exploration-exploitation tradeoff have found that variability
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...
Lastly, the findings of this study could imply that the optimal tradeoff between exploration and exploitation found in companies can be reached through market forces [37], as these are analogous to natural selection. 5. Conclusions Exploration and exploitation are two competing effects that combine ...
