English(EN) Understanding Uncertainty Sampling via Equivalent Loss

新框架统一了主动学习中的不确定性采样方法

研究人员引入了“等效损失”的概念,以更好地理解不确定性采样,这是主动学习中的一种常用策略。这个新框架统一了各种基于不确定性的采样方法,包括概率、边际和阈值方法。对于二元分类任务,等效损失与特定的链接函数结合使用时,可以展示不确定性加权如何在改变优化景观的同时保持校准。该研究还提供了统计保证,并分析了动量方法的优化行为,为连接采集规则与其诱导的目标和性能提供了一种结构化方法。 AI

影响 引入了一个统一的主动学习策略理论框架,有望提高模型训练效率。

    通过等效损失理解不确定性采样

    arXiv:2307.02719v5 Announce Type: replace Abstract: Uncertainty sampling is a classical active-learning strategy, yet the statistical objective induced by its query rule is often implicit. We introduce the equivalent loss, whose gradient is the original loss gradient multiplied b…
