Français(FR) Eluder dimension: localise it!

新方法本地化规避维度,以改进强化学习界限

研究人员提出了一种新的方法来本地化规避维度(eluder dimension),这是理解机器学习中乐观探索样本复杂性的关键概念。该技术为广义线性模型类建立了下界,表明传统的规避维度分析不足以实现一阶遗憾界限。所提出的本地化方法不仅恢复并增强了伯努利老虎机(Bernoulli bandits)的现有结果,还为具有有界累积回报的有限时间强化学习任务提供了第一个真正的一阶界限。 AI

影响 引入了一个新颖的理论框架,可能导致更有效的强化学习算法。

    规避维度:本地化它!

    arXiv:2601.09825v3 Announce Type: replace Abstract: We establish a lower bound on the eluder dimension of generalised linear model classes, showing that standard eluder dimension-based analysis cannot lead to first-order regret bounds. To address this, we introduce a localisation…
