随机森林Random forest简称RF是由Leo Breiman在2001年在Machine Learning2018年影响因子2809正式发表提出正如上一篇博客中写的随机森林属于集成学习中Bagging的典型算法总的来说随机森林就是在随机子空间中随机组合的自由生长的CART决策树Bagging得到的. Applications of machine learning Application of machine learning methods to large databases is called data mining. Introduces one function to model a particular view and jointly optimizes all the functions to exploit the redundant views of the same input data and improve the learning performance.
