Webb3 maj 2024 · warm_start = True should not be used for incremental learning on new datasets where there could be concept drift. Concept drift is a type of drift in the data model, which happens when the underlying relationship between the output and the input variables changes. To understand how warm_start = True works, I describe an example. Webb2 juni 2024 · 增量学习 (Incremental Learning)是指一个学习系统能不断地从新样本中学习新的知识,并能保存大部分以前已经学习到的知识。 增量学习主要有两方面的应用: 一是用于数据库非常大的情形,例如Web日志记录; 二是用于流数据,因为这些数据随着时间在不断的变化,例如股票交易数据. 另外在增量学习中,现有的增量学习算法大多采用决策树和 神经网 …
