在这个方向,我们希望有类似sklearn之于机器学习那样好用的工具包,可以帮助我们简单的应用各个模型。本周日上午9点,读书会邀请到CausalML创始团队的赵振宇,为我们介绍CausalML作为一个基于Python的开源项目的发展历程,核心方法,以及应用场景。 由智源社区、集智俱乐部联合举办的因果科学与Causal AI读书会第三季,其目标是:...
A common misconception is that the causal effect can be estimated solely by including the confounding variables as explanatory variables in a predictive model such as the Generalized Linear Regression or Forest-based and Boosted Classification and Regression tools. However, this is only true when all...
We evaluate the non-parametric change point detection algorithm changeforest37, and the results are shown in Fig. 5c. As expected, the method correctly recovers all the change points in the deterministic time-series data of the actuator input Lin. For the affected sensors, the method ...
在决策树的基础之上,还可以进一步做随机森林(Random forest),即首先使用Bootstrap的想法有放回的在数据中抽样,同时抽取特征(自变量X)的一个子集,进行决策树的预测。以上步骤可以不断重复,形成“很多”决策树,最终的决策结果由所有这些决策树的投票产生。这种方式相比决策树的优势在于泛化能力强。因果树的思想是什么?
