用来回归的树(Regression Tree)和用来分类的树(classification Tree)具有一定的相似性,不过其不同之处在于决定分裂(Split)的过程。 使用某些技术(Ensemble Methods),可以构建多个Decision Tree: Bagging Decision Tree:创建多个Decision Tree,通过替换训练集合,得到多个Decision Tree,最终得到一致的结果。 Random Forest Clas...

In the learning step, the model is developed based on given training data. In the prediction step, the model is used to predict the response to given data. A Decision tree is one of the easiest and most popular classification algorithms used to understand and interpret data. It can be ...
The decision tree is constructed by recursively partitioning the spectral distribution of the training dataset using WEKA, open source data mining software. The classified image is compared with the image classified using classical ISODATA clustering and Maximum Likelihood Classifier (MLC) algorithms. ...
