We can also fit a random forest and print out its confusion matrix in the same way. In this example, we set the forest to contain 500 trees, but you may tune this hyperparameter to find its optimal value. rf=RandomForestClassifier(random_state=random_seed,n_estimators=500) rf.fit(X_tr...
(全英语版)处理恶意软件的随机森林分类器算法(Random Forest Classifier On Malware) Overview 随机森林分类器是最近很流行的一种识别恶意软件的机器学习算法,由 python 编程语言实现;用于杀毒软件的传统基于特征码、签名、启发式识别已经无法完全检测大量的变体,因此需要一种高效和准确的方法。很幸运的是我们有开源的 sk...

Random Forest: 讲完了决策树的各种概念后,我们接下来,就讲讲随机森林(Random Forest) 先来给个随机森林的通俗理解: Random表示的是随机抽取,Forest就是说,这里不仅仅只有一棵树,而是通过一群决策树所构造的森林。那么,把random和forest的概念结合起来就是:通过随机抽取的方法训练出一群决策树来完成分类任务 Random...
