In this study, the impact of feature selection models on the classification performance of tree-based algorithms to determine the risk of heart disease is investigated. For this purpose, five different feature selection models are applied to the dataset taken from UCI ...
Tree-Based Classification "The classifiers most likely to be the best are the random forest (RF) versions, the best of which (implemented in R and accessed via caret), achieves 94.1 percent of the maximum accuracy, overcoming 90 percent in 84.3 percent of the data sets." ...
Cardiovascular disease (CVD) can often lead to serious consequences such as death or disability. This study aims to identify a tree-based machine learning method with the best performance criteria for the detection of CVD. This study analyzed data collec
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 ...

In the chart above, there are 150 samples in the top-level node. These samples are split into two subsets based on whether theirpental length. 在上图中,初始节点(顶层节点)有150个样本。然后根据pental length的标准,分成了两个子集。 Classification and Regression Tree (CART) 分类和回归树 ...
Mdl = fitrtree(Tbl,Y) returns a regression tree based on the input variables contained in the table Tbl and the output in vector Y. Mdl = fitrtree(X,Y) returns a regression tree based on the input variables X and the output Y. The returned Mdl is a binary tree where each branching...

ABC: Adaptive Binary Cuttings for Multidimensional Packet Classification Decision tree-based packet classification algorithms are easy to implement and allow the tradeoff between storage and throughput. However, the memory consu... Song, H,JS Turner - 《IEEE/ACM Transactions on Networking》 被引量: ...
It can be defined as supervised learning algorithms as it assigns class labels to data objects based on the relationship between the data items with a pre-defined class label. Classification algorithms have a wide range of applications like churn prediction, fraud detection, artificial intelligence, ...
