(3)带转换成本/延迟的MAB(Multi-armed bandit problems with switching costs/delays, Banks and Sundaram, 1994 和 Van Oyen et al., 1992) :当机器从一个项目转换到另一个项目时,会产生一个额外的费用或者造成加工的延迟, 这两项工作证明了对于带转换成本/延迟的MAB,不存在指数策略使得期望贴现报酬总和达到最...
Chapter 2 Multi-armed Bandits(多臂赌博机) 这里首先再次重申了RL和其他类型的学习算法的区别:RL会评估(evaluate)action的优劣,而非被正确的action所指导(instruct). “Evaluative feedback depends entirely on the action taken, whereas instructive feedback is independent of the action taken.” k-armed bandi...

Exploitation solves the Multi-armed Bandit Problem by exploiting the arm with the highest estimated value with respect to success times and rewards of previous plays. Exploration solves the Multi-armed Bandit Problem by exploring any arm that does not have the highest estimated value based on previo...
Chapter two: Multi-armed Banits# 区分强化学习与监督(模仿)学习等其他类型学习的最重要特征:强化学习使用训练信息来评估所采取的行动,而不是通过给予正确的行动来指导。 A k-armed Bandit Problem# 多臂赌博机问题:k个摇臂,摇动每个摇臂得到的回报都遵循一种概率分布,如何摇动N次最大化预期总奖励。
