Random forest is an ensemble of decision trees, a problem-solving metaphor that’s familiar to nearly everyone. Decision trees arrive at an answer by asking a series of true/false questions about elements in a data set. In the example below, to predict a person's income, a decision looks ...
随机森林(Random Forest)算法原理 集成学习(Ensemble)思想、自助法(bootstrap)与bagging 集成学习(ensemble)思想是为了解决单个模型或者某一组参数的模型所固有的缺陷,从而整合起更多的模型,取长补短,避免局限性。随机森林就是集成学习思想下的产物,将许多棵决策树整合成森林,并合起来用来预测最终结果。 首先,介绍自助...
Random forest is one of the most popular algorithms for multiple machine learning tasks. This story looks into random forest regression in R, focusing on understanding the output and variable importance. The package with the original implemetation is called randomForest. Companies Mentioned...
